You were asking "Why do we need a carve out for one particular group because of their genetic bad luck?". I'm telling you the reason is purely ideological: the right needs scapegoats and trans people are one of the current ones. Doesn't go further than than.
Trans people are explicitly on the receiving end of Republican's bigotry. They are constantly targeted through law and rhetoric, stripped of their rights and demonized at every occasions. Exactly like gay people were a few decades ago.
The Left's position on the issue is "let them be" whilst the Right's "they shouldn't exist".
