The problem is that most "anti racism" campaigns are just low ganging "white men bad" bullshit. They don't actually tackle the source of racism or actually do anything to help minorities, since that would cost actual money.
So they just attack white men, which alienates working class people because they are getting fucked by the system just like the rest of us schmoes.
In reality it's another way to divide the working class against each other, because Cletus from Alabama is getting fucked just like Wayne from the Bronx, but they are both being pitted against each other by the ultra rich and mega corps.
The right latches onto the anger of Cletus and tells him it's all Wayne's fault the left rushes to the side of Wayne and tells him Cletus is a racist piece of shit that needs to be knocked down a peg.
