One side of my family is very catholic. The church kicked out my father for being divorced. The rest of the family doesnt acknowledge I exist because my parents were never married. My mother's side HATES LGBT people so I end up having to defend my friends' right to exist to my own family. Between that and me being an atheist, very few of them maintain any relationship with me. I lost one half just existing and most of the other half when I dropped religion.
At the national level, women in red states lost their bodily autonomy because the supreme court and an entire political party have been captured by conservative christianity. And women are dying because of it.
I dont really know how you couldnt despise organized religion in general given what it does to people.
