Every cult has true believers.
There are still people who were in the Manson family, Peoples Temple, Heaven's Gate, Waco, all that shit wandering the streets today. The deaths and/or incarcerations of the leaders did not end the movements. I think the Manson prosecutor still has personal security.
Look at all the shit Scientology does to harass perceived enemies.
If you don't think some BLM whackadoodle could come popping out of the woodwork in 5 years seeking revenge for St. George, you're naive, frond.
