Just for the OP, Ignore Dr. Phil's comments as she alone has created her own identity of DEAF in all caps. which best I have figured means she is Hearing with her CI and can hear no sound without it and she would be identified as culturally Hearing by Deaf persons. There are 2 generally accepted terms deaf meaning the physiological/ medical of deafness as a loss of hearing and focus only on the medical ramification of such. A capital D Deaf is the cultural view of deafness with the primary requirement that Sign Language and ASL in the USA are the natural language of the Deaf. You cannot be Deaf and not know ASL... It is a culture based on common language, traditions, shared experiences, history etc..
Yes hearing people can be culturally Deaf. Many CODA's, some interpreters, some hearing spouses/ significant others of Deaf persons etc.
My source of expertise to comment on this:
B.A Deaf Studies, CSU Northridge.
I am Deaf, Married to Deaf and have 2 CODA's
PS, an easy way to see who is deaf or Deaf on a forum is look at their signature or posts, culturally hearing will often post the exact dates of their CI surgery, DB loss, brand of HA, CI etc. they all obsess on their hearing loss. Deaf just take it as a part of who they are and rarely will discuss such and probably don't even know the exact loss etc.
