They can call it anything they want, but the moment they leave their "culture" and try to police our language they have to justify it on facts and not just assert that they feel a certain way. It's completely irrelevant to medicine if they have a culture or identity based around their disability.

Can you explain your reasoning behind putting culture in double quotes. You may do well to remember you also need to justify your use of your own words. The medical industry does not (and shouldn't) have the last word on language relating to disability. It would well be worth you reading into the medical model of disability vs the social model of disability. In short: medicine doesn't always work out in the best interest of people with disabilities, hence society becoming more aware and accommodating of people with disabilities actually supports people with disabilities more than medicine.

I get what you're saying but I'm not going to legitimize a community based around the continued existence of a disability. As science advances, more will be cured and eventually everyone will move on and forgot about whether in the year 20XX people were offended by having deafness cured.

Sorry to see you've been downvoted. For those not familiar with the Deaf community, it is correct there is a Deaf culture with many people who identify as Deaf and indeed there is hundreds of years of history.
