This is great news. Now that we've proven the animals are conscious, we can put more resources into communicating and reasoning with them, and convince them to stop maiming, killing and eating each other. Peace on Earth, maybe within our lifetimes!
Literally nobody has ever done that. Try understanding his comment a different way. Like, say, that the human protections against violence preclude humans who chose to act violently, ergo if we extend that protection to animals, many of them would lose that protection as soon as it was extended to them.
To clarify, mtowle means 'them' as in 'the humans,' i.e. omnis will go to prison, be killed or endure some other form of violent punishment if caught eating meat.
Good luck with that. Maybe it happens, but I'm not holding my breath.
