It may seem surprising, but the above are wrong for the same reason as our treatment of animals is wrong. Racists or sexists categorize people as 'inferior' without actually looking at their individual abilities. They think these 'others' don't deserve the same rights, simply because they don't belong to the priviledged group (say the white 'race', or the male gender). Even if it were true that i.e. women were on average dumber than men (it isn't), denying them all the rights men have is wrong, because the smartest woman would still be much smarter than an average man. One has to consider the actual abilities, not the 'group label'.
It is obvious to everyone that torturing humans is wrong, and that when they suffer, they should be helped. Is this so because humans are 'intelligent'? Do the intelligent deserve more moral care and attention than dumb people? Obviously not. Because what matters is the capacity to suffer.
A human infant, or a person with severe mental disabilities, have the same (or lesser even) mental abilities and capacity for suffering as pigs or cows. If a company were to inflicted suffering in human infants or disabled people for a marginal benefit equal to 'some tasty meals', the public would be beyond outraged and scream 'nazi'. So why is it suddenly okay to do the same thing to animals, if they're just as 'consciously aware of suffering' as the above mentioned members of the human species? The answer that unfortunately, we're biased. Biased to an 'in-group / out-group' mentality. Biased towards racism and sexism. But we've overcome these evils with time and are now aware that they're wrong. We're also biased towards 'speciesism'. And as of now, not much seems to be done against it. We can't just assume that the interests of beings ought only be considered when they belong to the species Homo sapiens. What matters is the capacity to suffer. And if it's wrong to let infants suffer (even if they're orphans and no one directly cries for them), it's also wrong to let pigs or cows suffer (and chicken, and other sentient animals).
Killing is another matter. Is it wrong to kill (non-human) animals? Many vegetarians would say 'yes', yet some say 'no' in theory. If it's done painlessly, there's not much wrong with it because as long as the animals aren't self-aware (and only humans and maybe some other great apes seem to be), they don't have future plans or interests. They live 'in the moment'. Analogically, abortion is allowed too, even at stages when the fetus has some level of consciousness and definitely feels pain. So while killing non self-aware beings might not be intrinsically 'wrong', it definitely is wrong when it's done with pain. And since the common practice of killing animals involves scary transports, crowding and a bolt into the brain (that in a significant percentage of cases doesn't kill instantly), it's safe to assume that killing animals the current way is wrong.
To me, those reasons alone seem absolutely sound and enough, and even though I LOVE eating meat, I stopped eventually (though only after about a year of rationalizing it, despite actually being aware of the facts and the ethical case). But there are other reasons still:
