From what I've been reading about LGBT+ and their life stories, a bunch of them recall something from their childhood that confirms their current identity in a confirmation bias sort of way, like "guuh, I watch bambi", "my mommy told me it was ichy to wear women's clothes" or other situations along those lines and not just kids being kids. I think they are confusing their addictive impulse to act in a degenerate way with some kind of inevitability, be it genetic, soul-related, or whatever the fuck they believe. When in reality, they created this impulse, this vice by themselves, which could not have happened if they hadn't engaged in those degenerate behaviors. They made this mental construct, this bad habit, and they think that it is some kind of instinct that they cannot control or just that they don't want to control, that they have always been this way, and then they turn this addiction parasite into their identity. But that is more a porn/sex addict kind of side of the LGBT+, maybe there are those that aren't addicts, but they look like a really small minority.
It is like an alcoholic deluding himself into thinking that he was always an alcoholic because he really liked Barney from the Simpsons when he was a child and not because he drank excessively.
