DH thank you for your response. I will read some about these things and maybe have some intelligent questionsPlease Register or Log in to view the hidden image! I haven't made any judgements. One can always find a link to a website that supports your cause, so these things are pretty meaningless. And I don't have a defaut---because I don't know the science. And I seriously doubt that many people here (on both sides) have a firm understanding of the science either. This, of course, means that a bunch of people cut and past things they read on the internet, and ridicule the other side for being so short-sighted. The point that I want to make is that if you don't really know the science (i.e. you haven't figured it out yourself), then one has no basis to make claims of these sorts. So the question stands---does anyone here actually know what they're talking about, or is this information coming from third hand sources?
