It's a valid point
My teacher is a interpreter and has a sign name, however honestly her knowledge of ASL is amazing. 11 years of practice plus she is finishing up her schooling for it, started learning when she was 12. I find that as with anything and anyone, some people will accept you some won't. Some deaf people would love to talk to you, if you are hearing some not as much. I'm hearing but I can't really say it's necessarily a deaf thing. I was asked yesterday if I had a deaf name however, I don't believe the guy knew I was hearing I said "no I am hearing and have a no sign name" (in ASL of coarse). Seems to me you have to be generally excepted into deaf world to have a sign name be you hearing or not. Correct me if I am wrong.
