I'm not sure I believe in wide-spread conspiracy theories. But here in the UK we have a royal famiy, very vocal in support of organic and alternative medicine (at least in the person of Prince Charles).

I do believe ignorance is a huge problem, so is inability to dislogde an erroneous thought, so is vested interest in a certain idea.

However, I do believe history will vindicate us. After 4 centuries, we know the real author of Shakespeare was a woman. It sure took us a long time to get there, and sadly it will probably take another century before she gets recognised. But it's progress. And every person who becomes aware of the amalgam issue is a step forward in progress.
