Okay, we're definitely not talking about the same things. I'll clarify: you brought up data about a growing number of people who are LGBTQ, and I responded about whether it matters. Does that growing number have a negative effect on society?
Aaand now you're moving on to a completely different topic: early transitions. I don't really think I know enough about early transitions to make up my mind. If mistakes happen what is reversable and what isn't? What are the chances that a mistake could occur? How much does quality of life improve after such a transition (hey maybe this is related to your question about why they would like the transition done early)? Does an early transition open up options like fairly participating in sports competitions where a late transition is now imo a fairly gray area? A lot of this is already mentioned in this thread, but I haven't seen enough actual sources to go either way on it.
Oh and as a cis straight male, I'd certainly prefer to be called he/him and be very confused otherwise. If someone were to purposefully to try to push a different pronoun, I'd probably be offended? This is a pretty straightforward topic for me (note I do understand other people have differing points of view on the issue). If someone wishes to be called a pronoun different from what I perceive, I'll make an attempt to change what I say and they shouldn't be offended if I make a mistake. Requirements are silly, and intent matters.
