CFS vs Mental illness

I heard a piece on the radio yesterday. The piece was about researchers into CFS who were receiving death threats from CFS sufferers for researching CFS and it's possibility of being a mental illness.
How stupid are these people? They have research teams looking into their problem and they are frightening them away with death threats. Yes they may be looking into areas that you think are a waste of time, but once they hit a dead end they with look elsewhere. Yes maybe at a post viral solution. But for now give them space to work!!!

My biggest problem though is their obvious hatred of mental illness, they are helping promote the stigma attached to mental illness.

Let me ask one philosphical question of them, "if a researcher found a link to mental illness and a drug that cured once and for all. Would they take the drug knowing they had made threats on this researchers life?"
