Query: This author's anti popper zeal blinds him to the facts.

I'd seen a refernce to the book on an AIDS website that attempts to debunk the well-known and inconclusively-proven fact that AIDS is caused by HIV. The author, along with the others on this site, seem nothing short of zealots who need a soapbox to help in their shameless self-promotion.Lauritson's anti-popper stance is as unwarranted as his stance on what causes AIDS. He does a disservice to the public who will undoubtedly be mislead should they read his book.His brand of false alarmism is a shame.
