"Applied stem cell biology is quite complex,..."
That is the key here. You think it is complex, but looking at the postings above yours, and at least one followup to it, people are thinking that the FDA, scientists, the whole edumacationistic cabal, are making things too complex to preserve their authority. See for example, postings saying there's enough information out there that people can come to their own conclusions and decide for themselves. See how anti-vaccine kooks get copious air-time (any kooks, for that matter) - just because they can't see why the FDA is correct must mean the FDA is wrong.
And there's also this anti-government/libertarian sentiment (why do we need medical regulation, why do we need the dept of education, etc.). In some cases, there is over-regulation and some times regulation does lead to beneficial drugs getting to market later than otherwise, but the FDA exists because the record of the free market in medicine has only debilitating injury and death to show for it.
And I think we're finding this out with there off-shore stem cell facilities too. Only the failures never make it to the marketing material, so these treatments always work, so why should the FDA not let everyone get the benefit, right?
