PETA are not all Democrats. Left wing does not equal Democrat. Radical does not equal Democrat. These guys are advocating destruction of property, theft, and even murder. Do those sound like things Democrats endorse? ALF and their cronies are anarchists, plain and simple.

People tend to characterize Democrats as far left wing, when for the most part they're not. They range from moderate to somewhat liberal. If the scale of 'left to right' were 1 to 10, most of them would fall between 3 and 5. Most Republicans fall between 5 and 8. People at 9 and 10 are paranoid militia groups. People at 1 and 2 are anarchists. Both 1 and 2 and 9 and 10 want to remake society into their own image, and I'd say that fits pretty well with what PETA, HSUS, and the ALF want.

Saying radical animal rights organizations are all Democrats is like saying neo-Nazi skinheads are all Republicans.
