I’m a flexitarian. Meaning I have a mostly plant focused diet. But if invited to, say, a work event or a wedding or to dinner at my oldest friend’s parents house, I’ll eat a lot of salad, potatoes, and bread. Maybe even a bit of their chicken or beef roast to not cause offense or awkwardness. So, that’s my choice. I have long term dear friends who are vegans. I respect that. But I want them to contribute an appropriate dish to share with everyone if it’s that’s so important to them. That said, I think they should just eat and shut up. Do what works for them and leave other people alone. Judging and preaching at
your host and other people is bad manners. No matter how passionate you are, there’s no need for that. You don’t persuade people by bullying them. Am I wrong?
