Turn Christianity into a vehicle for conservative identity politics instead of a community and moral framework, and the people victimized by it will cease to identify as it. Simple as that.
In the U.S. you are likely correct. But in Spain, Portugal, Argentina and many parts of Latin America it was a strong supporter of fascist/authoritarian regimes up until the 70's and 80's. Also, up until the 19th century Catholicism was the foundation of very authoritarian and absolutist monarchies.
