Veganism

[Ivan Denisovich]

Legality is not morality.

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.
