An echo chamber is an echo chamber. Whether natural or artificial. Lemmy is extremely one sided. Dissenting opinions are not tolerated nor welcome (from a political standpoint). Perhaps less so than reddit as Lemmy user base is much smaller.

Because Lemmy is equally an echo chamber, and historically people do not like being reminded of inconvenient truths.

If I want an echo chamber, I’ll just go back to reddit. Bluesky is ass.

You’ll get your rent when you fix this damn door!
