The main reasons I’ve seen from vegans for not eating meat seem to be all about the morality of eating a sentient animal, the practices of the modern meat industry, and the environmental impact of it. And don’t have anything to do with the taste of meat.
Since lab-grown meat doesn’t cause animal suffering, and assuming mass production is environmentally friendly, would you consider going back to eating meat if it were the lab-grown kind?
As an omnivore I’ll admit the idea is curious, and while I wouldn’t personally partake because of cultural upbringing about cannibalism, I wouldn’t judge someone who did enjoy it the way I would an actual cannibal.
