Bro once called his son in law a gorilla for being dark skinned

No way people in the past had bigoted views?? Who could’ve possibly guessed that??!11!1111

Also MLK was a socialist.

Not all people did. That is a twisted version of history. But Marx was an extreme case. And MLK being socialist doesn't prove anything about Marx. Many blacks have been duped by the socialist movement (though I believe he himself would not be one in today's world). MLK was also a preacher. Many people forget that and try to be hateful and use his speeches to rile people up. But MLK himself has said that hate never changes anyone, only love does. (Hitler may have an argument with that, but we're talking about changing ppl for the better).

I know not literally *everyone* was racist back then, the same way not literally *everyone* believed the earth was flat, but racism was still prevalent back then. Hell, even blackface was still around when Marx was alive, you can’t tell me he was an “extreme case” back then.

it wasn’t always racism though. there were many people who weren’t racists. Modern history books look at everything through a racist lens. Blackface was around long after Marx died, but it wasn’t the norm. That’s like saying that because the KKK still exists now, racism is still prevalent.
