What you say is reasonable, and is not free speech absolutist. This isn't a No True Scotsman sort of thing. There are people on this very forum who reject out of hand any question that 8chan should be censored.
Another reply to my comment supposed my criticism means that the alternative is a Soviet surveillance state. Really?
I think the point is more that there's nuance in preventing speech (like censorship) and punishing the actions as a result of speech. I get that some would call those the same thing.
In the context of 8chan, I think there's a difference between allowing people to say whatever they want online and punishing the people that use that freedom to incite violence.
The part where it gets blurry to me is the hateful rhetoric that doesn't directly call for violence, but the only logical conclusion of the position is genocidal or otherwise racial violence. Talking about "invaders" or "American cities under foreign occupation" for example.
