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?
Vegetarian here. It's not something I'd personally buy or use in meals, as I don't really have the desire to eat meat. That said, if it happened to be in a dish I really want to try at a restaurant, sure I'd eat it.
