I know it doesn't matter, and is fully a side issue to this post, but I hate that "blacklist" gets brought into this. It's never been used to be "a list of black people" or something; that wasn't the original meaning, and that's not the modern intention. It's just a word that sounds like maybe it could have been racist in origin, but it wasn't. And that one makes me grumpy just as an annoying word person.
The real hot take was that we used the term black and white for people at all! If we could go back to the past and make it so we call it, like, Affo and Euro or something, whatever, it would have cleared up a lot of unrelated term confusion.
I mean, if we could go back and change things there's maybe some other stuff that would be more important to change... but among the changes I would make are those!
It's really easy! If you imagine that a black person and a white person could never be friends or spend positive time together, and then you saw a show that had them together, you might conclude the show is trying to convince you something is okay that you know is not. Propaganda.
If you imagine that a gay person is inherently wrong, and that bad things deserve to happen to them as punishment for their choices, and then you watch a show where a gay person is happy and normal and respected, you might conclude the show is trying to push an idea on you that you already know isn't right. Propaganda.
It's sad, and dangerous, but it's not complicated.
