This lengthy rant from near the end of his "Not Okay" episode of The Big Picture:
"...my favourite variation on this theme, 'Aw, come on, man! This is like the last place where it's okay for guys to talk like this!', as though some kind of sacred tradition is being preserved by not calling bullies out on their bullying. Hey, uh...genius? Lean your ears up real close. THERE SHOULDN'T BE ANY PLACE WHERE IT'S OKAY! BECAUSE IT'S NOT OKAY! It's not okay to harass women! It's not okay to 'slut-shame'. It's not okay to hurl racist and homophobic slurs as a form of violence. It's not okay to use 'rape' as a casual synonym for 'defeat'. And it's really not okay that I should have to explain that to anybody. I do not accept that sexual harassment, misogyny, bigotry or hatred of any kind is somehow integral to the fighting game community or any other community in video games or anywhere else. But if such a community does exist, yeah, it's wrong and should be called out as such and disinfected via sunlight. Of course, this will inevitably draw responses about 'free speech' and the First Amendment from people who do not understand either of those things. Free Speech as a legal concept only guarantees you the right to speak. It doesn't guarantee you the right to be heard, it doesn't guarantee you the right to be agreed with, it certainly doesn't guarantee you the right for your speech to not be challenged by someone else's speech, and most importantly of all, it doesn't mean you can't suffer consequences if and when your free speech is being used to cause harm to someone, which is exactly what sexual harassment, racial slurs and verbal bigotry are. That's not censorship. That's fairness."
In his video With Great Power Chapman challenges geek culture to be better than the mainstream culture that came before it. Like it or not, fantasy, science fiction and lots of aspects of "geek" culture are now part of mainstream culture. But instead of being tolerant geeks act as prejudiced as those who bullied them in the past. Instead geeks need to be inclusive and accepting.
