Veganism

[Disagreeable]

Yeah, that was the whole point. Just because slavery used to be legal doesn't mean that it has ever been moral. The same may be true of killing and eating non-human animals: and that's the analogy.

I'm not a practicing vegan. But it's a possibility.

Considering that humans are omnivores I wouldn't compare killing and eating animals with abhorrence that is slavery. It does nothing but cheapens any argument for immorality of eating meat and to be honest I've never saw them as being in any way convincing in the fist place.

It's not an argument to say that eating meat is in any way justifiable because we're omnivores. Just as it's not in any way a justification for being racist to say that racism is natural.

And it doesn't cheapen the argument if what's done to factory farmed animals, at the very least, is on a par with what was done to human slaves. You seem to be assuming that slavery is morally worse than consuming animal products when that's in question. You may say that it cheapens the awfulness of slavery to suggest that these evils are on a par, but it may be said that it cheapens to awfulness of consuming animal products, which is basically endorsing an animal holocaust, to say that these evils are not on a par.
