I am firmly anti-Russia, but I don't hate Russians. I am anti-China, but I don't hate Chinese people. I am anti-Israel, but I don't hate Israelis or Jewish people.
I doubt the vast majority of Americans would bat an eye at the first two statements. Why is the third one somehow more problematic than the first two?
I'm probably speaking out of turn here, but reporting a previous name is a simple matter of security, not deadnaming. I'm not trans, but I use my stepfather's surname and changed to that legally when I was 18. If someone called me by my mom's abuser's name to my face I would be distraught, but when forms ask me for prior legal names I just list it and it's not a big deal. It's just an identity thing.
The form isn't asking "what's your real name?" it's asking "have you ever been known by any other legal names?"
