I think it would be preferable if you didn't phrase comments like this in the inflammatory way you chose to phrase it.

Maybe that person is also tired with such egregious violation of animal right? Pigs are smart animal, and I think they deserve good life and the best way to help them is not eat them.
Nobody chooses the genes they are born with. Its a discrimination at its best. We stopped slavery probably 50 years ago. At past, I bet there were people like "Nope! I am not going to do menial job. Its my personal agent, so do whatever you want....".
