I was asked to chime in on this, so here we go.
The fighting game community is not special. There aren't special rules in place allowing everyone to act however they want and say whatever they want "because it's the FGC and that's how it's always been and that's how we want it to stay." That's just not how it works, not just if it is to be taken seriously or awarded any measure of respect, but also if you want to be a decent human being in any context.
When male:female ratios are out of balance, like in the hardcore video game community, people will tend to act crassly; someone's not there, you are less likely to take them into account when you say something, and that behavior gets reinforced when a subculture of insular boys that celebrates trash talking forms. In some of these articles I see the Starcraft II community being mentioned as an example of a far more welcoming and respectful gaming culture than the FGC, but it deals with similar issues thanks to the scarcity of women and the abundance of socially awkward male gamers. When a female gamer joined a Korean pro team, and it was revealed that she only had mid-league ladder status, she was met with a swarm of harassment and derision for receiving special treatment, even though the whole point of her being brought onto the team was to see if she could be developed into a talent and to further the acceptance of women in pro gaming. Different tone, same message: you're not welcome, you're not part of the club, you're inferior, go away.
Sexist, misogynist, harassing behavior is not appropriate; that much should be obvious. But it's also driving women away from all of these scenes, which benefits no one. Who wouldn't be for better male:female ratios in hardcore gaming and esports? It's not going to happen unless we take appropriate measures to address all this crap we see (or participate in) on a daily basis. That means condemning this sort of behavior and ostracizing the worst offenders.
Should this Aris guy be banned? I wouldn't shed any tears, and I think he should be actively prevented from having any sort of legitimate voice in the community in the wake of what he's said here, but it's a band-aid on a more endemic concern. So his statements are imbecilic and damaging, but they also accurately reflect the outlook of the fighting game scene (and the hardcore video game culture at large) to at least some degree. The controversy as a result of the statements can hopefully serve a positive purpose, though: let everyone reflect on how they act and what they say to women in gaming and be more conscious of what they're doing. It's a fight against entropy, ultimately; there's an infinite supply of fresh idiotic socially awkward teenage boys to try to screw with any progress that's made, but it's still necessary.
Edit:
The problem with pointing to specific women in the scene and saying "hey, look! they're totally into the trash talk and they take the sexist jokes and throw them right back at the guys!" is that it's selection bias; the only women you actually have in the scene are the ones that developed a thick skin before they let themselves be driven out by the onslaught of trash.
