TST sucks ass though. Their leadership is all abusive right wing hierarchical assholes and all they actually do is profit off of an image that they fight for abortion rights and such, when in reality they’ve never won a court case and have been time and time again completely incompetent in their litigations. Theres a huge community of grassroots actually leftist satanists and after being deprogrammed from TST they all try to come out about the abuses they suffered at the hands of TST leadership only to be sued into silence. There’s a ton of info about this, but a good place to start for those curious is the group Queer Satanic.
Megusta is much lower quality than the groups the OP mentioned.
