It's just stupid though. Some people get offended by (for example) "hearing impairment" because... it's implying they have an impairment. You do have an impairment, jeez.

It's different in groups too. I believe if you're profoundly deaf, and you sign and actively involved in the "deaf community", you're Deaf. If you're not, you're deaf. Maybe I have that backwards, but I don't really care.
