All of those comments were written from the perspective of a person who no longer 'exists' tangibly as they've transitioned.

Then perhaps what the transitioning person is looking for, is just creating a new account to go with their new self?

I'm not one of those who are affected, so unfortunately I'm without a sound rebuttal. You do raise a good point. Given that I'm not, someone who is may have more perspective that'd support one assertion vs the other.
