Just a side note, the presentation you were at was at an auditory oral conference, so I have no doubts the presenter made sure to share only what could fit into this bias. And let me guess the presenter was hearing... and there was no CART/FM systems provided, let alone an interpreter. It would fit in with your mindset if you can't learn to hear you're just no smart enough, and you all likely think your field of study is only for "intelligent" folks.
@deafdyke is right. A good number of these studies, programs and evem individual researchers are massively funded by Ci companies. Anything that only promotes one method is suspicious. The money trail amd dispropotionate number of non DHH just make that exponentially more so.
While we're on the topic of motives...
@Teacherofthedeaf you have yet to answer my question I keep posting time and time again. Why did you get involved with DHH ed and services to begin with? Since it seems you find everything DHH inferior unlike many hearing folks working with DHH because they're fascinated by Deaf culture/find ASL/BSL/Auslan beautiful etc.
