I used to think that pushing such content off a site or forum was futile and calling it for what it is on a site had value, I'm not sure that is the case anymore.
If you look on platforms like reddit and such where you have groups in subreddits calling for race wars, general hatred, and violence and of course the lesser efforts to just normalize hate takes place... there's no discussion anyway. In their own subs any hint of anything less than absolute commitment to their talking points of the day, ever changing theories, and general hatred is an instant ban from their subreddit(s). Then they venture out spam their fake news articles / take over other subs and push their message with endless streams of new accounts. There is no discussion, just constant spam, memes and etc.
We've seen topics like Gamergate, incels and such (while not that tasteful to begin with) quickly pulled to the extreme and go from something about "gaming journalism" or general angst to an identity movement steeped in fear / hate, harassment, and for some actual violence.
I suspect there may be some value in ushering these people away, if only to prevent recruitment of some others who otherwise might avoid their message that fear or dissatisfaction with life and other problems can be explained with hate.
