The whole thing is paranoid lunacy, but I just want to point out that he thinks that straight white men
don't get thrown slurs at them online. He's likely separating insults from slurs, which is already exceptional, but he's also of the belief that straight white men (and don't forget, he's two thirds of the way there) instantly recognise each other online - not even necessarily through voice, but also just through usernames on Twitch - and are instantly polite.
'Don't attack a fellow gamer,' they think, 'my fellow straight white men will not be insulted by me this day'. And whatever they were going to say suddenly becomes an act of support and solidarity against every minority, because when you're a straight white man, why pick just one of them to hate when you can hate all of them? Meanwhile, of course, no non-SWM has ever been anything but polite and respectful online and certainly never used slurs against anyone they don't like, even fellow minorities. Innocent victims, all.
It's like how they never understand the point of the Farms isn't to laugh at minorities. It's to laugh at potentially anybody, only there's fuck-all other places where you're allowed to laugh at most of the people we mock. We have threads, even subforums, about straight white men, but they ignore that and just focus on how we're one of the few places you can use nono words and also point out that, say, the lunatics at ResetEra include a racist black furry, numerous delusional men who pretend to be women, and of course a man in an arranged marriage who is very, very upset that he's the one being oppressed, while complaining on a gaming forum about everything except games.
