The problem with 8chan is, it's not a cohesive whole. Each board is individually ran and the global moderators won't get involved unless it's content that's blatantly illegal. Not all boards there are the same. Not all the people there are the same. The problem is the hateful supremicists all congregate there. /pol/ is the board where most of them hang out. Other boards have nothing to do with politics and have completely different kinds of people that post there. There's even a /leftypol/ devoted to leftist politics that contains no white supremicists.
