I always hear the the Falun Gong are a cult, but I never really hear what makes it a cult. I skimmed the Wikipedia page and it only really said that Falun Gong is a spiritual movement. The oppression of them seems kinda bad in my opinion, but I am very uninformed.
Edit: thanks very much to everyone who replied
In addition to everything said in this post, they’re actively dangerous as the biggest platform of medical disinformation in the world. For starters they’re the biggest anti-vax group in the US, and have been banned from Facebook because of it. Additionally, their Chinese branch peddles fake cures for Serious illnesses which many gullible people are conned into doing rather than seeking actual treatment.
