I have a friend who is a bit, erm, fervent about his political beliefs and thoughts on religion and such. He's a bit out there, but always came from a place of compassion for humanity and wanting what's best for everyone. And once or twice he has conceded that he was wrong about something.
However. The other day he expressed a theory that the Holocaust never happened. Or if it did, it was all a global conspiracy led by the West to excuse the creation of Israel. After all, he claims, nobody ever learned about all the medical advancements the Nazi party made (which isn't true, I recall in several classes reading that there was debate in the medical community for years about the ethics of using Nazi research)
Also Bill Gates created Ebola for population control and vaccines are a way for the government to subdue you.
So what crazy conspiracy theories have you come across lately, or do you think they're even crazy at all?
