Eating meat will become a personal choice when it affects no one but the person doing it-
no animal death, no environmental devastation, no exacerbation of world food disparities, and no health crises.
Until then, incredulousness at having one's meat-eating criticized is about as rational at declaring those pesky people who oppose your slave-owning or wife-beating "self righteous and high and mighty".
