This behavior is common enough that it creates a chilling effect for anyone who disagrees. Why take the time to craft a reply correcting the poster if it will likely be hidden from everyone? And so you end up with echo chambers.
The effect is quite stunning on some topics. For example: Quite a few people on Bluesky believe the Trump assassination attempt in Pennsylvania was staged[1], that the Charlie Kirk assassin's text messages are fake[2][3], and that the recent ICE shooter was a false flag.[4][5][6] Notice the amount of engagement these posts have. Thousands of likes, with little to no disagreement in the replies. The lack of feuding is what allows people to believe these falsehoods.
