The front page picture of Ross Cameron ( ("Vitriol, far right style", February 11-12) conveys a disturbing, fanatical hatred. The appalling slurs unleashed at the so-called Q Society rally make laughable complaints about lack of free speech made by the likes of Cameron, Pickering, Hanson, Christensen, Kirralie Smith and Bernardi. Cameron no more represents the Christianity he hypocritically flaunts than paedophile priests represent Catholicism or IS the large majority of Muslims. Hanson, now strutting her loathsome stuff again courtesy of Turnbull's political naiveté, first castigated aborigines, then Asians, and now Muslims. Despite the noise this extremist mob makes and the media attention they crave, they are a small minority repulsive to the many who understand that it is not tribalism, toxic intolerance and irrationality that make for progress but co-operativeness, forbearance and reason.

Vast tracts of NSW are now classified as "Fire Risk: Catastrophic" ("Sports off, hospitals brace for sizzler", Febraury 11-12). Penrith had its hottest ever day at 47 degrees on Saturday.

A day at the zoo can be an expensive exercise at the best of times ("Taronga Zoo's harbourside eco resort plan slammed", February 5). Granted to cost of upkeep for our iconic 100 year old institution would be high, although one wonders whether the cost of admission may restrict some visitors. If the zoo's management and board have sufficient capital to undertake the proposed works, then the question must be asked why can't that be reinvested into improvements consistent with its central purpose, a zoological park? Pandering to a demographic looking for a high cost experience does nothing to accommodate those who want to live the experience of the pleasure of a day at the zoo.

Malcolm Turnbull's loud tirade against Labor's "clean energy 'ideology'" is an attempt to show leadership to his right wing, and to claw back voter popularity.

We received the most charmingly addressed letter this week from a 91-year-old reader in Deniliquin,  addressed: To- The Editor, Sydney Morning Herald,Perhaps Pitt St, Sydney GPO NSW 2000. Clearly the postie who delivered it is working hard for his money - but many letter readers think this is not so for his boss Australia Post CEO Ahmed Fahour. HIs $5.6 million pay packet was the subject of many angry letters this week. Last week we were inundated with letters from America to Australians -apologising on behalf of their president for his phone manners and behaviour in general. This is unprecedented for us here at the letters page to have so many American readers seek us out to write enraged by their leader. This outpouring on our letters page even made it in the US press. Next stop Hollywood letter writers!  As Carolyn Richard of Enmore joked this week: "It  looks as though the Beverley Hillbillies have taken over the White House - no-one seems to know how to behave." Nonetheless - as our regular correspondent from Georges Hall, Rosemary O'Brien points out there still remain many Trump fans. "Jeff Swanson (Letters February 10) writes from Washington to tell us not to fret, and that he has no time for Trump. I have friends in Arizona who think Trump's the ants-pants. Doesn't prove much, eh?" Thanks to all who wrote in response to our request for examples of letters that changed lives. They were funny, inspiring and one - Peter Skrzynecki's bought this tough cold-hearted editor to tears. Which brings us to the question raised by our 91-year-old Deniliquin writer's correspondence. Has anyone every tried to write to the managers at Facebook, Google or Twitter (either old school snail mail or email) and got a real life response?

Nice try, Mr Turnbull, and rather nicely choreographed too, but as football coaches tell their slower learners: "play the ball, not the man" – it was pretty poor technique ("PM unleashes his inner attack dog", February 9). Yes, we did want to see that you could speak passionately, forcefully, and even aggressively about policy issues (perhaps climate change or asylum seekers?), but we also agreed with you when you said that the Parliament needed to restore civility in debates. The likely place for heated personal invective is in your cabinet room, not in our Parliament's chambers. Oh, and the "sycophantic social climber" tactic (better known as "duchessing) was an old and overused British Tory's insult to Labour politicians thought to be "rising above their station". If you still really want to be like Keating, at least come up with some original forms of abuse. Peter Russell Coogee

The Royal Commission into Institutional Responses to Child Sexual Abuse has brought to light thousands of incidents of sexual abuse of children by people in authority in the Catholic Church.

It should have been Malcolm Turnbull to form a new, enlightened and progressive "coalition" of like minds.

• February 7

Another politician voted in as the candidate for one party leaves to join another or set up their own party or become an independent. This is not right. It is an abuse of the electoral system and the voters.

Donald Trump is correct to describe the deal done between a politically expedient Australian prime minister and an outgoing American president who did not have to concern himself with political consequences as a "dumb deal".

In light of Donald Trump's fiery phone call with Malcolm Turnbull, we have received an unprecedented number of letters from Americans apologising for their president.

• FEBRUARY 4

As a citizen of the United States, I apologise for the nature of the telephone call from our president, but that would become a full time job.

In a week in which President Trump gave Australia a stark demonstration he isn't going to play by the rules, it seems apt that we reconsider one of our conventions.

It’s not that easy to get a letter published in the Herald, but things could be worse.

ould we please stop falling for the term "clean coal" ?

If Malcolm Turnbull is to govern for all Australians, climate change must be at the top of his list of objectives.

Our Prime Minister's failure to condemn Donald Trump's new immigration laws is indeed pathetic but if it allows just one family to escape the gulags we have created on Manus Island and Nauru it will have been worth it.

Malcolm Turnbull turns to water as soon as a matter of actual substance comes to the fore.

Regardless of which issues Gladys Berejiklian chooses to champion now that she is Premier, ("Early tests for Premier as byelections loom", January 28-29) it is important to remember that she is still a member of the same political party as the former Premier, was a minister in that Premier's government, and will still be subject to the same party faction, lobbyists and developer pressures.

I wish you luck, Ian Macfarlane, battling for me and millions of other Australians of Anglo-Celtic ancestry against the likes of Barnaby Joyce.

Barnaby Joyce shows, yet again, how out of touch he and the Liberal Party are with reality.

Mark Porter: Thank you for the publication of my sesquicentenary letter.

• JANUARY 21

As a recently retired public school teacher and Deputy Principal, I'm surprised that my first letter to the editor in forty years of readership should be in defence of a Liberal politician, Mike Baird. The majority of comments (Letters, January 20) contained the generosity of spirit of a Donald Trump tweet.

The stark contrasting of Donald Trump's juvenile twittering and the measured intelligence of Xi Jinping has serious implications for our own foreign and trade relationships.

Exponential population growth brings exponential growth in the complexity and difficulty of governing.

Trump's inauguration is set to redefine America's role from that of a global player in the promotion of democratic values to a nation ideologically obsessed with its own self-preservation.

After spending so much taxpayers' money on weekend trips with his wife to Broome, I hope Mr Cormann at least had the decency to pay for his own cigars.
