I think this is a flaw in the current state of Lemmy. There’s so few posts compared to Reddit that random people will find your 3 upvoted post in all. This leads to people outside of the community dominating the discussion.
You can also see this with other communities. Everytime I see the conservative one in All it’s a non conservative OP being insulted by other non conservatives, because they assumed OP must be a conservative to post there.
There being an anti tech community won’t solve this issue. I think the most accessible solution is moderation.
