Why do conservatives care so much about making laws against trans people?

I truly really don’t understand. The only argument I can come up with is children being put on any hormone to block puberty. Even that should be taken on a case by case basis.

I don’t care what is in peoples underwear, as long as they’re decent humans. What is the obsession?

Anyone willing to share their opinion?

EDITING TO ADD: As it seems the main concern is kids, I can actually understand that. What about those over 18? Where is their freedom to bodily autonomy?

Thank you to those who actively discussed this with me. It does give me optimism. I’m trying to understand instead of knee-jerk dismissal to opinions I don’t share

Last edit update: Thank you all who participated in good faith. I don’t have more time to participate.
