I see Facebook/Twitter/Reddit in the unenviable role as having to police minimum local standards across the world's largest online community. They also have to do it while running a publicly traded company in the USA, which means they need to optimize for minimum moderation costs.

s/going against the current flow of ideas //
I straddle the line between US liberal/conservative depending on the issue. I've been labeled lot of things by both the majority opinion holders and minority opinion holders. It doesn't matter. People need to put on their big boy/girl/whatever pants and realize it doesn't matter what you are labeled. People call you far worse behind your back... the internet just allows you to hear it and reduces peoples' social filters.

I treat {4Chan, 8Chan, 9Gag, etc} as a proxy for "long tail opinion holders" who gather in the same place.
I'm sympathetic to the idea that being a social outlier with no outlet for discourse/self-importance/identity/hope is strongly correlated with those extremism/terrorism, but that doesn't preclude 8Chan from being part of that process of extremification.
I listened to a podcast over the weekend about a Philipino guy who worked as a Facebook moderator. He quit for many reasons, but among them PTSD, nightmares, attraction to sexual images of children, attraction to bestiality, etc. He might well have had those same tendencies before he moderated for Facebook, but the exposure to that content was what accelerated his problems.
The Chans are an exposure channel. They probably help in popularizing fringe ideas, but they also attract window shoppers looking for identity and an ideology that social misfits might be willing to try on. Shutting down the window shopping isn't nothing (although I will admit I don't know that it can be done while preserving the intent of the principle of Free Speech).
