PeTA should be talking about treating animals with undue torture, like the examples shown in this video. I disagree with their stance that eating meat is prima facie immoral, unhealthy, and unnatural though. If we are to ever boycott eating meat, it should be because the farmers are treating them without dignity even as animals (i.e. a living being). Of course they shouldn't be treated on par as humans (or maybe they should? it's complicated but I'm inclined to say no for now), but they should be treated with some sort of dignity.
I wonder why they shock the cows before they bleed it but they don't do the same for the pigs. That was pretty sick what they did to the pig.
I'm sure this video shows the reality of what's going on, but selected examples of torture (mean farm workers cussing at the animals) are probably just that -- selected examples. I sure for every asshole working at the farm there is at least one who isn't like that. But the entire packing process is probably more or less the same with the other packagers, so that might be something PeTA should focus on.
Plastering billboards of cancer patients was not an ethical treatment either, so PETA should be careful about being fvcking hippocrites that can't treat people as well as animals. They have some valid points, but the reason that they turn most of us off is because they extend their arguments to moral/naturalistic arguments that don't hold water... and nobody like getting spammed by overzealous people, no matter what their intention (e.g. religion, peta, liberals)
