AITA for not letting my friends enjoy their boxing and mma matches while i'm over at there places?   


For some background let me explain, when we were younger my friends and I used to watch boxing and sometimes mma (like ufc) matches together and enjoy them but I lost contact with the group for a good few years. I kind of changed myself and didn't like violence or those type of sports anymore, I meditate and promote non violence. We all recently we reconnected and one friend invited me to his house, we all got together for a party, they had drinks, food and everything was prepared, it was great. One friend suggested he put a ufc event on tv and I refused him. It started a huge argument over it and they all said I should leave but as i'm one of the guests, I can't have a say what goes on tv? They all seemed really pissed off and one of them was even insulting me which he was serious about? AITA? I thought guests were to be treated with some respect? He can watch boxing or ufc or whatever when I leave surely?
