Perhaps read "Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming" to understand the basic strategy of groups/websites like GLP. That way you can be a bit more selective in your information sources. Well, that presumes you actually want to understand.
