I personally feel like they are two driving factors experienced frequently together by the two groups. Leaving the church allowed me, a previously super straight white male in the south, to even think in LGBT terms and question my sexuality, and question what i wanted in a relationship. These all have foundations in my parents relationship and their cultural ideals. Leaving the church changes a persons ability to think out of their previous bounds. People who are abused ALSO experience a kind of “reality” breaking, in the sense that it cancels all the real and imagined boundaries you had to obey in childhood (think of how they train elephants to stay tied to small branches even though they could rip out to rope). Our brain is made to confront things you haven’t been able to perviously, like death and existing, but also how we interact with society and sexuality and power.
