My Jewish roommate is telling me I'm not allowed to use the oven for my food in the apartment we BOTH pay for. He then calls me unreasonable for being upset and feeling disrespected because of it. (The apartment CAME WITH the oven. It's not his personal oven) AITA for feeling it's unfair that I can't use what I am also paying for?

Edit for clarification since a lot of people don't seem to understand that some Jewish people will only eat kosher and there are special rules to that. I'm not Jewish. I respect the religion, but it's causing issues. He's trying to tell me I'm only allowed to cook kosher food and store kosher food in the kitchen or fridge as well. He expects me to change my way of life for his religion. Which i believe is disrespectful to me.
