Well, I skipped most of the posts that had to do with confusion in the context of the purpose in this discussion.
I can't speak comfortably as I think I'm not well versed in the operations and proceedings of the deaf world in reality. But I did feel I can contribute my own experiences.
I think the sum of most of my personal experiences is very similar to melissa's short autobiography. Being unilateral makes me feel like an outsider any hearing or deaf culture. All my life I've been systemized to flow with the main valve rather than being able to try alternate routes. This image predominated much of my childhood that at some point early on I refused to acknowledge deafness, I just wanted to be OK and not treated differently from the teachers and students in the class. It wasn't until later I realized I was doing myself more harm than good, something that took maturity to reach.
The trend has always been towards remedying deafness in the medical community, this is probably an undisputed statement that doesn't need backing to prove it. The public's consistency in adhering to this trend is the main question being asked and that’s what I'm guessing makes up for the shedding of the lackluster approach. It must have been due to the lack of empirical evidence in the science department that it dropped around the 80-90’s. Now with the situation back and booming, some of the people here seem to be fixated on the prospective issue of “deafhood” being eradicated.
I'd like to think it is more of a paradigm shift. Tousi mentioned economy which could be a prevalent contribution to the current focus. Looking back, we've had an increase in scientific evidence in just the past decade or two. The DNA human genome project completed, advances in artificially engineering DNA, stem cells, symptoms and results of STI's blah blah so on. It is a part the reason to why I believe the paradigm is shifting towards medical approaches once again.
The root of the cause has to do no more, no less than with human impulse to "fix" things to their liking. The only thing that is holding this back is people have varying definitions of "fix", although this principle that seems to run rampant within the scientific community. I'm honestly not surprised though, doctors (or scientists rather) want an explanation for everything in their field.
This is how I can observe that some of the asl-only communities have gotten out of the opinionated grasps of the current world's flow, aside from the few self-centered types that want to be "unique" - reasoning for those would come from deviance theories from the sociological perspective.
However the deviance model shouldn't be limited to one side, it would mold both ends of the fence. It's just more prevalent in observing it from a pro-deaf side.
I’d also like to chuck it in that some popular role models that are also affecting the opinions and decisions of people, even if just minor to an extent. Parents trying to fit the shoes for their kids beforehand, or the kids grow up wanting to be like one of those superstars.
Marlee Matlin.
Adam Savage.

Just a few I can think of the top of my head.
