Their website is just loaded with biased propaganda and specious science of the most contemptible level. Some of their issues I don't even understand. For instance, GM crops? These are crops designed, among other things, so farmers don't need to use nasty old pesticides. How the hell is that even an issue? Face it hippies. GM grops are here to stay.
Mind you, originally Greenpeace had good intentions (and I think a lot of members still do) but somewhere along the line they lost their way. For shame. It's very telling when one of Greenpeace's largest critics is its former founder and president, Patrick Moore who preaches that environmentalism is about sustainbility and pragmatism, and not close-minded extremism.
And the scary thing is, there are worse green groups out there like Sea Sheperd. I suppose one can argue that groups like Greenpeace serve as the so-called Hegelian* antithesis that clashes with the thesis and ultimately creates the final synthesis - a happy middle ground. However, I fear that this extremism of the greens doesn't achieve this and only broadens the divide.
How are you suppose to gain community and government support when you preach bullshit and have the image of being a bunch of drug-addled dread-locked hippies? Simple: you don't.
