We get it, you don't like sports. As a geek who grew up playing the occasional sport but not really enjoying it, finding a sport I truly enjoy at the age of 26 (baseball, not so popular in my country) and following a team has been eye-opening.
Sports fans have welcomed me, and been very accommodating explaining parts of the game I don't understand.
And then there are other geeks like you - that have an almost visceral reaction to the idea that people would enjoy something like that. I don't understand people who have such a negative view of others' happiness.
Oh I'm sure you have some kind of horror locker-room story where the football team did something disgusting to you, but sports wasn't what did it. Those alpha males would have some something similar even without the context of sports.
