The point of my comment is to point out the absurdity of the equivalences drawn in the grandparent:

> Imagine your children being born into one of these farms.

> You might argue non human animals are different, but why does that matter? Black and white people are different, why would that difference justify enslaving one group?

I don't claim to know where the exact line is, but thankfully, I don't have to, because the world doesn't run on ethical guidelines, it runs on power struggle. Grandparent was quick to draw the analogy to black slavery - I'd like to point out that black slaves were powerful enough to fight for their own freedom. Cows and chickens aren't. We're gonna eat them because that's just how the world works.

Of course, if someone very powerful becomes obsessed with animal rights, and uses political power to ban meat, I guess we'll stop eating them. I'd be very sad if that happens, but again, that's just how the world works.
