Stop addressing them as “normies” would be a great start.
Can’t speak for rest of the Fediverse as I’m not super active on microblogging anymore, but at least here on Lemmy, there is such a strong “in” culture and quirky skewed perception of the world, and often times come off as actively hostile against those that do not share the same quirky skewed world view. The anti-AI, anti-corporate, would rather shoot myself in the foot if it’s not FOSS, etc kind of views, with their own strong vocal proponents, comes off as unwelcoming. People are addicted to socials because of the positivity they can get, not the negative sentiments that’s often echo’ed.
Amongst those that doesn’t share the kind of view, you’d already be looking at an extreme small minority that might be willing to give the platform a try, but as long as the skewed perception of the world dominates the discussions, you can expect them to go back to main stream centralized platforms where they can get more main stream view points based discussions.
