This is a dumb argument. Just because we eat meat doesn't mean cultural standards don't apply to us. This is the exact same argument some christians make against atheists when they accuse them of having no ethics.
ah this is super late, but
it's not the same argument at all.
i honestly want to know what the difference is to people. if it's simply SOCIETY ACCEPTS POULTRY CONSUMPTION, BUT NOT DOG, then that is a bad reason imo.
i have pet chickens who have names. i take care of them, pet them, cuddle with them even! to me there is no difference between eating a dog and eating a chicken.
