this is an opinion that can only come from a place of privilege

Talk to me or don't, but when you some dumb, meaningless shit like this it's not really a conversation you're trying to have. Since you don't know much of anything about my background, and I know even less about yours, let's try to evaluate each other's words instead of making buzzword value judgments about character.

To get back to the conversation: You have it the wrong way around. The ideas that were once too dangerous to talk about were that black people aren't subhuman, not that they are. In fact, there is a really large body of literature from post-Civil War until like the 1930s trying to use data to support that point (and not from backwater Southerners--Harvard was the biggest and worst offender for this type of "research"). It was only when more voices were let in that change started to occur. One thing I agree with you on is that there is never a true marketplace of ideas. That's a fantasy, but it's a good fantasy, not a bad one, and one that we would be wise to try to strive for. In fact, I have it on pretty good authority that's sort of the point of this here website (privileged information, you might even call it). The abject ridiculousness of ideas about, say, genetic inferiority, only get exposed in a world in which alternative narratives are allowed to thrive.
