Great episode! This is one reason why I'm so disappointed when I see fellow geeks and nerds attacking furries and bronies. I'm not a fan of either, but after going through school as a nerd because I played RPGs and computer games I'm not going to bully someone for their own niche entertainment, even if I think it's odd.
(And yes, the sexualized elements of these fandoms are pretty weird . . . but so are the sexualized elements of mainstream geek and nerd properties.)
A big part of the problem, however, isn't with nerds and nerd culture, but the fact that there are people who will attack groups on the margins regardless of what is mainstream. The so called frat-boy stereotype is a good example, the 'frat-boys' today are doing things that would have gotten them beat up by the 'frat-boys' of twenty years ago. (I feel a bit hypocritical using that example seeing how many college fraternity members don't fit this mentality.)
However, with no many key cultural figures coming from a time geekery was not mainstream, it would be nice to see more of a push towards acceptance and civility. It's the sort of responsible thing that past cultural figures didn't push enough, and it would suck to have a culture I grew up with maintain that status quo.
