That has not always been my experience, although I can see why you on Lemmy.World would say so (bc it defederates from lemmygrad.ml and hexbear.net, where most of the hostility across the Fediverse concentrates), but indeed the average interaction here is much more positive than on Reddit (even though the worst, e.g. if you ever comment in ChapoTrapHouse@hexbear.net, is significantly more negative than Reddit ever was allowed to become by the admins).
