Cringe comment tbh. Religion is a net neutral institution. It can be nudged in any direction. Majority atheist states are not less oppressive than majority religious states. America does have a uniquely large amount of Christianity-inspired cults tho. I would say this more of an indicator of America's failing/non-existent social systems, rather than an inheritant feature of religion.

Cults, mafias and corrupt monopolies exist primarily, when the state fails at least in one key area. They act as competitors of the state. Competition in science, art and economy is great. In governance, competition means public chaos and oppression. Multi-party democracies are the only exceptions (to some extent).
