It's also a lot of bots. They are here too. For example, just say China plus something negative about them, in a thread about China. Easiest downvoted one can get. Make sure it's a fact and not whataboutism, to avoid contaminating the test.
It's almost always instantly. Like sometimes second after posting. Then it either snowballs or it goes back into positive. But initially, be it on Lemmy or Reddit it happens. I'm not constantly complaining about China, the handful of times though, it's super obvious. Doesn't happen on other topics.
It's two downvotes (at least on lemmy.ml at this point in time). Is it hard to imagine that 2 out of 16 people could dislike seeing someone say that anything that doesn't fit their narrative is the result of bots?
That's weird, because it also has 2 downvotes for me at the moment (which means it can't be some weird federation issue), but assuming that you originally saw 2 downvotes before I came along, then something something can't be right because I am one of the two downvoters and I only saw the comment some hours after your comment in this thread (judging from the timestamp of my comment) (or maybe I visited the post once, then came back to leave a comment?).
