This ignores that 4chan is widely known as the cesspool of the internet and attracts those types. It’s like going on Hexbear and being surprised at the communists. People gather where their banners are. Shit attracts shit. This reduction is apt.
Sure it kind of does some good ish things sometimes, but more often than not, it’s just an internet mob internet mobbing. That’s essentially all it is: chaos waves constantly crashing back in on itself. Any good that comes from it is incidental at best.
Also, defending 4chan on the wider Internet is a little odd, 4chan itself revels in its shit reputation…
Not with that attitude
