Is gender on the same level as race though? You can't change your race but you can change your gender - both in cases it's warranted (gender dysphoria) and in those it's not (otherwise).

Also it's disingenuous that you say religion is not a part of a person's identity, when in fact there are people to whom it's an important part of their identity as a person. Sure you can argue relision is a choice - and I can grant you that - but then it's the same with non-gender-dysphoric transpeople;they just chose a different gender than their biological sex for an arbitrary reason.
