Edit: Interesting how most any comment I make on HackerNews indicting the history of racism is heavily downvoted. Uncomfortable facts are often deemed irrelevant, uninteresting or inflammatory to those whose beliefs are most challenged. I’m not going anywhere.

The high-order bit on HN is: what kind of discussion is anything likely to lead to? Are we going to get a curious conversation about (in this case) animation? Or yet another bitter battle about (in this case) race? HN is for the former, not the latter—we're interested in things that haven't been repeated countless times already. All scorched earth is the same.
Edit: Unfortunately it looks like it looks like you've been posting this sort of ideological battle-bait quite a bit: https://news.ycombinator.com/item?id=20451846, https://news.ycombinator.com/item?id=20429974. And we've had to warn you before. If you can't or don't want to use HN as intended, we're going to have ban you. I don't want to do that, so please fix this.
Also the novelty of my comment was the connection to minstrel cartoons which is adjacent to the topic of animation. Not many people know this. It's not like I am just making random shit up.
If you know something about animation that other people don't know, that's great and of course you should share it. But how you go about it matters. If you share it in a bomb-throwing way that's guaranteed to start a flamewar, any curiosity in your comment will be the first thing to vaporize. Curiosity always is.
While I agree with your sentiment, I don’t know about this case.
The only bit it debunks is the specific image cited, which is in turn a modern comment on the pre-existing links.
