Every important medical innovation of the last five hundred years has been ridiculed, undermined and ignored by doctors and the medical establishment. Every single one. Hand-washing, antibiotics, and the dangers of smoking, just to pick a few.

Just because the establishment doesn’t like it doesn’t mean it’s not a good idea.
(On the other hand, there are plenty of bad ideas the establishment doesn’t like as well).
