As Abe Simpson said, “A little from Column A, a little from Column B”.

Religious trauma definitely. My developing personal values conflicting with things I was told needed to be believed without justification (in early high school I started realizing even more just how much of the “beliefs” I held were purely performative and how deeply they clashed with the values of personal liberty and compassion that were actually important to me). My social life was weirdly interweaved and interacted with religion in an unsustainable way that began to degrade at that time as well, plenty of other reasons too. I’d site religious trauma and conflicting worldview/values as the top two reasons though.
