The fact that Greens act in part as a natural brake on society is not a complete loss. There exists a need for some caution in any field of human endevour, and they provide it. The a**hole is not a very elegent or beautiful part of the body however we would all concede that it does perform some neccesary functions. That the Greens are a**holes does not detract from their essential nature in the scheme of things though they do come up with a load of sh*t a lot of the time.
