Maybe, for me, this is more about "minority culture" in general than "deaf culture" in particular. "Deaf Culture" is an adaptation for people who can't hear. Once you can hear, you no longer need the social adaptation.
I'm a member of a minority. For those of you who don't know, I'm black. At one time, black people were denied access to educational opportunities an that in turn lead to fewer career prospects. My parents and grandparents worked very, VERY hard to give me opportunities and I took advantage of them. I finished high school. I attended college. I earned a Master of Science degree. Consequently, I have a pretty good job. I've been accused of turning my back on "African American culture" because I speak like I paid attention in school. I don't use the "What up dawgg?" vernacular that some other people (who happen to look kind of like me) do. I have been accused of having "forgotten where you came from", as if I didn't come from a middle-income, racially diverse suburb.
Once we were no longer denied access to quality education, it was no longer necessary to speak AAVE (African American Vernacular English) or "Ebonics" that some people like to call it. We were able to learn standard American English and it benefits one to do so.
I understand the desire for deaf people to adopt the mantra "There's nothing 'wrong' with the way we are." but in reality there is. You can't hear!
I'm sorry if people take it personally that their social adaptation is becoming less necessary for future generations. I'm sorry that they feel lonely or abandoned. This is a good thing. This is progress. This means that fewer people will have to live with the handicap(sorry for the loaded term) of not being able to hear.
