Scientologists apparently have the answers to mental illness. HIV denialists swear that HIV doesn’t cause AIDS. But very few people are actually buying it—enough to cause trouble, surely, but the Tom Cruises and Peter Deusbergs of the world aren’t winning any Nobel Prizes. Why not?
Because they offer nothing. HIV researchers and clinicians have emptied out the AIDS wards, but the denialists have done nothing. Psychiatrists (and yes, their medications) have helped people lead normal lives. Scientologists have done, well, nothing but sue critics.
The difference between the scientific approach to medicine and the denialist approach is that one offers solutions, while the other does the intellectual equivalent of leaving a flaming bag of poo on the front porch.
Remember this—denialists offer no solutions, only conflict.
