I’m saying that you’re discounting in-group membership as a tangible benefit. That being part of a loving and accepting community can be a huge positive in spite of larger society’s negativity.
I suspect you’re wrong.
Errm…maybe, pick a lane?
You seem to be implying, here, that “social factors” can only be the majority consensus society’s. But influences from subcultures/small groups, such as affirmation, love and acceptance from your own group, are also a social factor.
Although I wouldn’t say that causes anyone to be trans, it certainly means they will be more willing to accept being so.
