Not a good example. “Defending X” is a much stronger requirement than just “pointing out that a specific argument against X is invalid”; the latter is done by everyone who likes seeing good arguments rather than bad arguments, and isn’t a sign of liking X.

(The most pro-russian (as in, supporting the russian-ukraine war) stuff I’ve seen was various memes from lemmy.ml and lemmygrad that ended up in popular. I’m having trouble finding a better example than that; in particular, because Lemmy’s search is bad and doesn’t seem to allow for searching recent comments from a specific instance, and also refuses to give me more than a few pages of results.)
