I don't know, there's still a lot of needless hostility; it's just around different topics.
Lemmy skews even more heavily left than Reddit and it's still too small to attract organized political trolls, but topics like FOSS vs Paid open source vs closed source gets heated fast. Look at the Sync for Lemmy threads; it's a mess in there.
Of course. I'm just saying pray for the ad-free version then. If you are going to use it.
