Idk what's more damaging, the fact the Jedi were actually a burocratic police force (don't ask me how) or that they were a creepy cult that were taking children away to train them in their ways
They were always both...people just didn't think that deep about it. There's plenty of reasons for PLENTY of people to have beef with the Jedi. Imagine the Catholic Church circa 1490 and add in a little bit of mysticism and you basically got High Republic Jedi. They are a military, political and social force in and of themselves. It's no wonder people didn't mourn their eradication en masse.
