Given that they only have 2 downvotes, I'd say that's just Lemmy being Lemmy. On other less confrontational topics, I usually will say some mundane comment, and still get like 1-3 downvotes. And it scales too. If you have 10 upvotes, you might get 1 downvote. But if you have 50 upvotes you might have 3 downvotes.

One time I just said "FUCK ICE!!!" and got over 100 upvotes, and 3 downvotes. So I wouldn't take these downvotes too seriously. Some people just have no life.
