It isn't science. They can't say that it works, clearly it doesn't and even if it did they have no way of knowing how. So it isn't even demonstrable
I think at the point aware we start discussing whether or not we give children as young as four years old hormone blockers and puberty blockers we need to hit the brakes. It seems this was a pot of water that was slowly brought up to a boil. But it's gone absolutely bananas. I think the way we stop this crazy train is 2 a first stop conceding language. No bizarre pronouns no gender fluidity no non-binary. This nonsense is absurd. And the absurdities today will become the standards tomorrow unless we keep them absurd.
What are the list of things this community and it’s represenatives want to change? Is there a cohesive list or summary?
Most of the trans community as well as its supporters will agree with you. Very few would want children to be given such things. It's one thing to allow the child to present as a given gender. But the vast majority know that young children getting such drugs is bad. Now as far as at puberty, that is a much larger divide. I agree with you to a point about the pronouns. As to other supposed absurdities, women and blacks voting would have once been considered an absurdity. Children choosing their own spouses would have been considered absurd. Even the very idea that people could choose their own leaders, instead of the positions being inherited was absurd at one point. Things that have been standard for thousands of years, are now absurd, and what was absurd is now standard.
From merely a Medical perspective, altering development of a patient during puberty is very BAD medicine, violating the initial precepts of "Do no harm" and initial development of a patient mentally as development process in stages before many factors mature and progress. Blocking development in favor of a different format causes irreparable harm as there is too scant a data base to work with.
