It’s maybe unpopular, but people should feel bad about it, especially they should feel shame. I don’t feel it either, who knows this for decades, and even tried a few times. But I should. There is exactly zero pressure regarding this.
Based on how people react to me simply being a vegetarian in their presence, without me commenting on what either of us are eating, people do feel shame. It's just that the shame is outweighed by the pleasure of eating whatever.
I don't think people should feel bad about it, but at least informed.
A better thing would he to have a carbon tax, so you have higher vat on beef than poultry and higher for poultry than eggs.
