Lemmy and reddit are closets in one room of one floor of one building, where they kick out anyone who won’t scream “Fire!” along with them. Those are echo chambers. Anyone telling you that half of the country is fascist, is pushing an agenda and using fear to influence you. Or they have been influenced and are simply propagating the propaganda.
That’s a really good use for bots, since new users haven’t seen the best posts and may actually enjoy discussing them. Older users can simply move on, filter from their stream if they get bored of it.
