Amanda gives six reasons why PETA and Operation Rescue are deeply similar. Some of these (eg, `They think women are just bodies to be manipulated for their ends instead of full human beings', or `Both have a strong, irrational loathing for science.') are absolutely unargued, and actually false if read too literally (I've known PETA members who were feminists and scientists and even one woman who was all three).
On the other hand, some of her points are spot-on:
Neither seems to care that much about the real life well-being of the objects of their advocacy as they claim to care. Anti-choice groups uniformly oppose contraception and sex education, which are the only proven methods of reducing the abortion rate overall. PETA has an unsavory history of liberating research animals only to have them die from the stress of their liberation.
Then we have this one:
Both prefer to advocate for “victims” that are silent and therefore can be projected onto. It’s no coincidence that people who are bereft of arguments and prefer sentimental whining and shock tactics prefer causes where the supposed victims are not able to articulate their own desires. Animals/fetuses give them their excuse to work out all sorts of other feelings, and not just disgust and anger towards female bodies, though that seems to be part of it.
I find this simply bizarre. Members of both groups believe that there's a large class of beings who (a) deserve more legal rights than they enjoy now, and (b) cannot advocate for those rights themselves. Operation Rescue members think that foetuses deserves a legal right to life, and they stage demonstrations and so on as a form of advocacy on behalf of foetuses, because the foetuses (being non-rational beings confined to wombs) cannot advocate on their own behalf. Similarly, PETA members think that non-human animals deserve certain legal rights, and they stage demonstrations and so on as a form of advocacy on behalf of those non-human animals because (lacking the ability to use language and understand our legal system, etc.) they cannot advocate on their own behalf. We might disagree with the premiss that these beings deserve these rights, but that's a totally different issue. Given that someone should advocate for these rights for these beings, and that they cannot do it themselves, it follows immediately that someone else is going to have to be an advocate for them.
Being an advocate on behalf of another is not a vicious activity, in and of itself, and it's certainly not automatically an act of projection. If projection is a vice, and if members of PETA or Operation Rescue are engaged in their advocacy for no reason other than an act of projection onto non-human animals or foetuses, then the problem here is the projection itself, not the advocacy per se. At most, the fact that these beings cannot be advocates for themselves might make them more likely to be projected upon, but I don't think this is true: what else are racism, sexism, classism, etc., but the projection of the interests and beliefs of the dominant class onto other classes?
