I generally don't eat meat most meals because it's way messier to clean up after cooking compared to beans, rice and veggies, but eating out I will have meat.
Plants are living things too that we raise, exploit, systematically molest and slaughter, do vegans not care about that? I get the reducing impact so there's no shame to that, but once lab formed meat is a mainstream product, that would seem to me to be the most ethical nutritional consumption in my view. My mental model of what little I know of it is that while the cells are living it is grown more like a crystal which is non-living.
