Whether you are trans or not, I feel like people voting for you should be aware if you have changed your name so they can do some googling and make sure you didn’t get into any controversy or shenanigans before you changed your name.
Which is what the campaign trail is for. This isn’t an application to take a seat, it’s a petition to run. Ask yourself how you as a voter have ever interacted with one of these forms.
I understand you aren’t defending this action, but theorizing about rational historical uses for this, even uses well outside this incident, only serve to add to the cloud of false rationality that bigots will wrap themselves in to defend this BS.
