I mean actual proper research, not CIA propaganda. I want to learn what truly was censored, both when it comes to politics and culture like books or film, and actual material reasons why.
Preferably stuff that destroys the typical Western bullshit about no freeze peach lol, I want to put it against Western censhorship and propaganda.
I agree with this. I think the best way prevent organized religion from undue influence over public policy, or over individuals in bad personal situations, is to provide reliable and complete public services that are typically provided by religious groups in capitalist countries. For example, addiction support groups. Religious persecution just feeds into martyr complexes.
