The excuse that 4channers are all just innocent, mischief-making kids and it's the rest of society that's the real problem is really starting to wear thin.

If someone says they're only fucking goats ironically, they're still a goatfucker. If a community is being racist ironically to the point that actual racists take its shit seriously, mass shooters shout it out in their manifestos, and that community harasses and doxxes people for racist reasons, then that's just a racist community. If someone gets off on the outrage that racism generates, then they're just a racist and an asshole.

Irony is not magical fairy dust that can be sprinkled over one's actions to make their consequences disappear. And really, at this point I don't think we can give 4chan and the like the benefit of the doubt that it's all just memes. Eventually, if you wear the mask long enough, you become the mask. 4chan became the mask a long time ago.
