I don't really mind religion (I'm an atheist) but sometimes people who involve religion in every single thing piss me off down to the core
My mortal enemy is jewish, which I'm perfectly fine with, I actually think it's a really cool religion, but back when I went to the same school as him he would get all mad whenever I said "Jesus!-" in response to getting spooked by something and it annoyed me so much. It annoys me so much cause I see people from basically every religion say it when they're scared by something anyway, therefore the person's religion doesn't even matter for this!
