Eeehhh... though I agree with the sentiment, I think differentiating that being trans isn't a choice still very much matters, even in this context.
The choices that people refer to usually when it comes to gender lie more in how one chooses to present their innate self and what forms of care they choose to engage in to affirm that presentation (i.e. gender affirming presentations/care in this context).
Instead, hateful bigots, transphobes etc. mistake the choice of presentation of gender for the supposed "choice" of identity.
Trans people have to navigate a society that continually tells them they are lying to themselves and "choosing" to be someone society says they cannot be. This is genuinely tragic and horrible.
No one should ever be made to feel excluded or so alienated from the society they live in as to wish they were not the identity they know themselves innately to be. That is akin to effectively killing them, and that is why these hateful ideologies need to be put in the grave.
