I see lots of hateful activity, from "boogaloo" groups that hide their violence fetish behind euphemisms and jokes about revolution, to "satirical" posts about the value of white identity and culture over other cultures and races.
The other day I came across a website whose purpose was to collect the full names and photographs of (white) women who date outside their race - specifically, women who date black men - and the (white) men who date women like that. Said site has a section dedicated to women who were hurt or killed by their partners, and labels those women those who "paid their toll" for dating outside their race.
I haven't seen any meaningful action by any of these groups except that website I mentioned, but the activity is there if you care to find it. It's something that worries me, specifically for my partner - who is a woman of colour.
