Sadly, the answer is yes! There are whole online communities of white men who do nothing but stalk, harass, and troll white women online. I've seen it. There aren't just the Andrew Tates of the world, whose job they believe is to exploit white women for sex and money, but whole communities like the MGTOWs and Incels who fantasize about raping and killing them on their various Reddit pages. White men talk a good game about valuing white women but that's all it is. What they're really more interested in is harming, dominating, and killing other groups of people in their name. These men covet white women which is not the same thing as caring about them.

You should be glad you don't know about the existence of some of these places. I think most well adjusted mainstream people don't know about them. I know about a lot of them from places that chronicles their activities like We Hunted the Mammoth, (which is a safe place to discuss what is seen and heard in those spaces).
