We've got a strange sort of confusion about political terms in America. We call Republicans "conservative" when they are really reactionary. We call Democrats "liberal" when in fact the entire party is profoundly conservative. How can this be? How can everyone but me be so very wrong about everything?!?!
Well, first off it isn't just me. There's a well-defined psychology involved here, called
Authoritarian Personality. This was sharpened by Dr. Bob Altemeyer into
Right-wing Authoritarianism. Fun stuff to read about, because it explains why Republican politicians and their supporters are all dishonest pieces of anti-American shit... that's my conclusion, the research is much more subtle and unbiased. *grins*
Republicans like the label "conservatism" because it covers up the fact that they are way out of the mainstream and hold radical and usually failed views. They have a delusional view of "common wisdom" that drives a big chunk of their attitudes. The Democrats allow themselves to be called "liberal" because it sets them apart from the right-wingers without actually requiring them to do much of anything but go along with the flow.
Moving beyond the mistaken "conservative/liberal" concepts, there is also the incorrect assumption that some causes or actions are inherently "conservative/right-wing" or "liberal/left-wing" when they are really neutral. Tax cuts, for instance, are basically neutral. A religious belief that tax cuts are the answer to every problem in every situation despite all evidence to the contrary is an ideological position promoted by the right-wing, but it is just stupid. Animal rights isn't a "left-wing" cause... and, in truth groups like PETA are as right-wing as can be. The definition is based on the psychology behind the organization, its leaders, and its members.
There's a great episode of Penn & Teller's Bullshit that completely tears apart the PETA leadership, starting with their head Ingrid Newkirk. The chick is a wanna-be Hitler from all accounts. There's tons of hypocrisy involved too: one of the leaders uses medicine made from animal parts to keep herself alive while telling others that their diseases shouldn't be treated at the expense of animals. PETA euthanizes animals all the time. The dishonesty in the name of the cause is just like any other right-wing group.
Further, there's nothing "ethical" about their treatment of people OR animals. When I let my pets "free" because PETA thinks pet ownership is "unethical", who is going to feed them, keep them off the interstate, or give them a warm bed to sleep in on cold nights? My pets are part of the family, they love me and I love them and it would be a betrayal for me to do anything but keep them here with me for the rest of their lives. At the same time, a chimp in a lap or even a thousand chimps aren't worth as much to me as a single human being who could be saved by medical research. And I know as well as every sane person that medical researchers don't use animals because they get off on the suffering of other beings.
What PETA is about, is control... the sort of control that goes along with right-wing authoritarian psychology. It isn't about the animals at all. It is about telling people what they can and cannot do with their lives, based on an inflexible dogma... inflexible unless it interferes with the behaviors of the leaders. They want to make us eat what they approve of, wear what they allow, and just follow follow follow. It isn't about what is best for people, or for animals, or anything in between.
The hypocrisy is the same as any right-wing group. Bush demonizes Democrats while claiming to be improving the "tone" of communication in Washington, Ted Haggard preaches about morality while paying hush money to guys he had sex with and snorting meth off a gay hooker's cock, and PETA's VP uses insulin from animal sources to stay alive while attacking all medical testing on animals. They euthanize most of the animals they take in, the bastards.
When you look at their behavior and attitudes, PETA is clearly right-wing... just like all evil fundamentalist nutjobs.
