Yes, it means exactly that. As in, nerds who have lived in their own geek culture bubble all of their lives, aggressively and prejudicedly judging sports culture from the perspective of their own comfort bubble, without ever truly experiencing it with an open mind or truly trying to understand why people enjoy those things and behave that way. Jock-bullying. It's very common in nerd circles, if only as a reflexive against the injustices against nerds, both real and imagined.
It's comical/depressing because nerd crowds are generally very self-congratulatory on how open-minded, liberal and intelligent they are.
And then this kind of reflexive antagonist behavior against jocks bubbles up, and we're forced to realize that no, just because geeks paint themselves as these smart and open-minded people does not mean it is true.
Sometimes, they're no better than bullies, insulting ways of life that they've never tried, simply because it is different or because they are expected by their group to dislike those things.
