I can't help but wonder why is it so bad about CI?
It's a matter of how you and others look at it. If others look at it differently and you don't like it, just ignore them. For me, it's not the CI itself that I have a problem with, but how the person acts after getting it.
What about it that considered an threat to Deaf Communty/Culture/Identity?
It's almost like a hearing aid. A person who truly follows "Deaf Culture" doesn't wear hearing aids since they are proud to be deaf and see no purpose of doing anything other than being... deaf. That's why there are a lot of "unwritten rules" in Deaf Culture. No cochlear implants. Only ASL. 100% deaf families. Etc. (I knew one deaf guy who actually refused to date a deaf gal cuz she had hearing parents and it didn't meet his vision of "Deaf Pride".)
Also, it's a matter of perception. They feel that those who get CI will stop following Deaf Culture or stop identifying themselves as deaf. Of course, that actually depends on the person... not the CI.
How is it different than hearing aid?
A hearing aid only magnifies sounds as it goes into your ear canal. It also depends on the kind of hearing loss you have. Some people have total hearing loss where they cannot hear anything regardless of what kind of hearing aids they wear. Those are the type of people that are likely candidates for cochlear implants. Others have some loss in hearing, but can hear with the use of hearing aids. I'm someone like that. If you were tlk talk directly into my ear (without wearing a hearing aid), I would be able to hear you. With a hearing aid, I can understand what's being said on a phone. So, I don't see any need to get cochlear implants.
With cochlear implants, it's pretty much the same for everyone. It taps into your nerves and makes you hear. How it differs? I don't really know. I guess it's just a matter of how our nerves can handle the implants.
Why can't you be deaf and have CI?
That's the exact same question I ask everyone else. Even if you got CI, you're still deaf... period. What is "deaf"? It's when you cannot hear like a normal hearing person. There are different levels of deafness, but they all are the same... deaf. I might hear better with a hearing aid than another person who wears a hearing aid, but we're both the same... we're deaf.
When you take off your CI, can you hear? No. Exactly. You're deaf. Some people refuse to see it that way. Why? It varies on the individual.
Why it have to be "you got ci? Ur not deaf anymore" or something that implied that we were trying to fix our hearing or to try to be hearing?
Either they are too strong-willed with their own beliefs or they had bad experience with people who got CIs. I've had bad experiences with people who got CI, but I don't let it bother me... until that person actually changes for worse.
Some deaf people have deaf friends who got CIs. After those friends got CI, they would stop signing and stop attending deaf socials. They would start trying to be oral all the time and hang out around hearing people. When they are around deaf people, they will talk orally and not sign... with an attempt to show that they are "hearing" or "better". These things result in ending friendships. So, when it happens to these deaf people... they get defensive when another deaf person gets CI.
Again, it varies on the individual. I was simply stating the most common excuse that I've heard from a lot of deaf people.
