And now presenting our fabulous third loon, Dr. Mohammed Al-Bayati.
Al-Bayati is a belligerent HIV-denialist, most notable for his involvement in the aftermath of the Eliza Jane Scovill case. He has published a HIV-denial book and runs a company called Toxi-Health International. Known hand-waver when pressed on these things.
A good discussion of his work is found here:
He is a pseudoscientist who also flirts with the anti-vaccinationists, and is a full-fledged conspiracy theorist.
Diagnosis: Self-unaware belligerent zealot, victim of extreme confirmation bias; impact uncertain.
