This is probably a hammer and nail thing, but having just heard a podcast about disinformation campaigns (https://samharris.org/podcasts/145-information-war/), your comment shares some traits. The podcast discusses that one of the main things "they" (those behind disinformation campaigns) do is putting groups up against each other in various ways, highlighting the differences rather than the similarities. Regardless of whether you're actively trying to do that (I would assume not, you're probably unaware of the effect this type of comment has), this is exactly the type of comment that creates an us vs them environment and highlights the very, very worst stories of what you perceive to be the other side. It's one of the least constructive things you can do online.
