I've met way more people who made hating vegans their whole personality than I have vegans who mention their lifestyle outside of the context of being offered something non-vegan.
And how many have we seen make bacon their whole personality? Or Ron Swanson wannabees who think eating a steak is gender affirming care. No, this is a ridiculous argument. Every group of people is going to have self-righteous idiots.
I don't see which part of my comment implies that I don't feel that way about humanity, nor how it's relevant. Humanity was able to coexist just fine for thousands of years. These issues were caused by capital.
