You first make the claim that your chosen diet must be safe because if it weren't safe there would be evidence to the contrary. Then you dismiss those people who try to bring forward evidence to the contrary as liars. You can't have it both ways.

It's funny that you should bring up Atkins and then suggest "following the money"... Atkins Nutritionals sued some of the people that you are labelling as liars, and lost all of their lawsuits. If there's one thing I've learned from my two decades living in America it's that when a corporation loses a lawsuit to individuals here, the individuals are probably barking up the right tree.

Have you considered the possibility that what you are terming "liars" is just "people that disagree with my strongly-held belief"?
