Both the meat-centered diet crowd and the vegan crowd seem to be about equally awful about being judgy about what other people eat. I eat a semi vegetarian diet. I'm not a vegetarian but some of my meals are. Both camps seem equally happy to give me hell.
I try to hope that most aren't really like that and, like with homeless people, we just seem to notice and remember the worst representatives of such groups because the rest are so quiet as to go unnoticed.
To be honest, if one day there's lab-grown meat available in every store with comparable quality and prices to animal meat (!), I will inevitably form some sort of opinion on people who still pick animal meat.
Meat eaters will still get heat from those who oppose the production of meat on ethical grounds. There, the question of who enjoys what is a distant consideration compared to the death and suffering of those being eaten.
What makes you think that? I'm a vegan who's been involved in animal rights activism for four years, and I've never met another vegan who opposes cultured meat on ethical grounds (or for any other reason). There are plenty who are excited to eat it, in fact.
I can't even think of an ethical argument against cultured meat.
life experience teaches me that if many people start to accept this, they'll start to push it on others via legislation. (see: vaccination. No talk of force until >50% was vaccinated, suddenly forcing on others became feasable and desirable for them)
