I think most people agree: potentially torturing human brains is bad.

I think most people also agree: torturing pets is bad too. Maybe like a 1/10th as bad as torturing humans, but still bad.

Yet despite all that, we MASS TORTURE MILLIONS OF NON-PET ANIMALS EVERY YEAR ... just so we can all have cheaper Big Macs.

P.S. If you disagree with the above, I strongly encourage you to prove how right you are, by researching what factory farming is, how widespread the practice is, and whether what they do to their animals amounts to torture. Please, look that up and "prove me wrong".
