I agree with you about a transgender person who is 23, but not about anyone who is claiming to be transgender at 13. That is way too young to be sure of such things, and peer pressures/influences exist.

The current backlash is mostly caused by the hardcore activists pressuring for "the alternatives are either gender-affirming care or SUICIDE! SUICIDE! even for 13 y.o.'s"

This attitude is so hysterical that it cannot stand for long.
