Are you referring to Dave? If so that is disingenuous.
Don't you train your dog to defecate and urinate on command?
Are you against the training of animals?
Isn't that slavery? Paying your pet with food when it pleases you?
Are you saying we can eat cats because they can't be trained, so easily?
Quite, in much the same way you keep your dog indoors and train it to defecate and urinate when you want them to?
Then why do you keep dogs, can't you see how inconsistent your argument is?
That is why we are a higher animal, except there is little need of training an animal about to be slaughtered.
And there aren't many leopards or hippos in civilised Western Countries, that also as it happens has a population with the lactase persistent gene. It's not all coincidental.
