Yes. The close relationship between humans and dogs has existed for many thousands of years. No such relationship with pigs has existed. Whales are endangered animals while pigs are not. Can we have the "some animals are more intelligent than kids with learning difficulties" line, as espoused by people like Singer, just so we can have the full set? That said, the treatment of animals is appalling and meat free is the way to go.
Pigs were domesticated several times in prehistory, perhaps as long as 15,000 years ago. Certainly 10,000 years of humans living in close contact with pigs is close to irrefutable. So actually, you're wrong: there has been a close relationship with pigs for a similar time-scale. Just the purpose of that relationship is different. And even then, pigs (especially miniature breeds) have been kept as pets for a long time, and dogs are eaten in some parts of the world too. So it's not so clear cut, actually.
As for whales, would you consider eating them if they weren't endangered? What if you were in Japan or the Faroe islands, where it's considered less-than-taboo to eat them?
There's no reason to trot out some old Singer line about people in vegetative states, it's not relevant to this discussion. The point is, both you and mx wcfc recognize the meat industry as bad and the latter even sympathises with this "action" (and I'm not sure I do, to be honest, I'm just jumping on the aversion to speciesism as a concept) but still feel the need to justify our relationship with animals as "that's just the way things are" (see you argument of dogs v pigs). I don't just accept it, the way things are, re: our consideration of different animal species. I'm questioning it. But I don't think bombing abbatoirs is going to be particularly helpful in the "cause" or whatever, if the final goal is mass uptake of veganism.
I'm not vegan, btw.
