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?
If it’s vegan (is fetal bovine serum still an input?) then yes.
Any vegan who says no is saying so for some other reason besides veganism (ick factor, no desire, environmental considerations).
If your knee-jerk reaction to this is to downvote because “what kind of vegan eats meat?” - consider why you went vegan. Was it for the animals? Well, if lab meat allows us to produce meat without animal suffering then it’s vegan…
