Weren't some PETA members convicted for putting explosive devices on places that were supposedly treating animals with cruelty? These people by any means, extremists.

Meat is murder... tasty, tasty murder.

I blame Linda. She started it :dry:

Its the suffering of animals that makes them so delicious

They don't seem to realise that the abusers come from a very small part of the meat 'industry'.
However, I didn't think branding meat that was totally not kosher kosher pretty bad. I wonder if that happens to hilal food as well.

Please. No one is going to align themselves with some of the acts that PETA has apparently committed. There are very few problems I saw with the video posted, and it seems worthless to discuss how awful PETA is when the general point they push is legitimate, unless anyone is in danger of actually contributing to their financial situation.

He's promoting PETA. If he was speaking out against animal cruelty in the meat industry without any such affiliation then I wouldn't see the problem. In fact it would be commendable as something does need to be done to improve standards in the industry. But through aligning himself with PETA, that effectively saddles him with all their criminal baggage too.
If people didn't contribute to them then they'd be out of business. It's thanks to people like McCartney that they're doing so well.

The only thing I heard was "show a friend this video." It seemed to be more about the argument than the organization.
His involvement definitely helps, but it seems like PETA is the best way to get information like this video out, even moreso because topics like this start.

I do not see any difference whatsoever between the harvesting of crops or other plants and the slaughter of animals. Unless you can photosynthesise something has got to die. Promoting vegetarianism or veganism as the only 'moral' way to live is pathetic and short sighted.

QFT.
/me is chewing on his home made cheeseburgers.
Best dead cow ever.
[I wonder if PETA also promotes that organic bullsh.t.]

The video is theirs and on their site. It's an endorsement, no matter how little he's shouting about it. He might not be as fanatical about it as, say, Tom Cruise is about Scientology, but it's still an endorsement.
You wouldn't appear on a white supremacist website if it meant you could talk about the working conditions of children in Nike sweatshops. McCartney's appearance on a video by these terrorists is equally ill advised.
Topics like this that centre on how terrible PETA is and completely ignores any animal welfare issues raised in said videos, you mean?
PETA undermines any cause they fight for. Regardless of how right the cause is, their involvement is damaging.

When you take into account the number of animals that die as a result of pesticides, harvesting etc, it's outright fucking ludicrous. Animal cruelty can be greatly reduced. There's no denying that. But to expect to end it entirely is typical PETA insanity.

Whatever argument I was going to make in his defense turns out to be meaningless...
From PETA's Paul site...

Says Sir Paul, “I love everything PETA does, especially the title. People for the Ethical Treatment of Animals—I don’t see how anyone could have a problem with that.” Click here to join online."
Yeah - the video is still being seen. It's beneficial for their cause no matter what we talk about. And as far as their involvement being damaging, if the only thing people saw was this video (like myself), their involvement wouldn't seem to hold any implication at all.

Especially veal. Mmmmm, love me some dead baby cow.

Haha! Oh, wow. I didn't even see that. Yeah, clearly his definition of ethical and theirs differs somewhat. Or at least I hope so. Either that or he's really starting to lose it now.
True. When people are unaware of the dark underside of the organisation, it's probably pretty agreeable. But even after a quick scan of their site the insanity begins to show through. Like their goal to end domestic pets (by any means necessary).
