you know a whole heck of a lot, and that many of these seemingly qualified people are severely deficient in one or many ways (S&C coaches, dieticians, etc.).
At the same time, that sort of supreme confidence that so many professionals are so wrong makes me, someone with no knowledge of the area, wonder if your opinions are largely based on unprovable theories rather than fact. That is, if it's so clear like you make it out to be, why aren't you revolutionizing these fields?
To be clear, I'm not saying your wrong; I have no basis to doubt your arguments in any way. Instead, I'm saying that the generalized criticisms — if not attacks — on huge majorities of professionals make me (a reasonable, I think, reader) wonder if you have some odd views that are causing you to criticize everyone else.
