I was called immature, narrow minded, and petty for this. I won't date a woman who is a fan of a sports team I hate. I went on two dates in the last month. They had on a Seahawks jersey and the other had on a Dodgers jersey. Seeing these two girls in the jerseys, I told them it wouldn't work because I hate your team. They told me I'd be single for a long time because I don't give people a chance. I told them you're right I don't, and walked out. I'm emphatic about this standard. Does this make immature and petty?
