I would submit that a lot of the idea that "vegans are obnoxious" comes from defensive projection. I know a decent number of vegans. I've known more at various points in my life. (I'm not one; I don't have the inclination or the discipline if I did.) And I have observed non-vegans transmute "no thanks, I'm a vegan" into a perceived attack and perceived moral superiority when it was not intended waaaay more than I've seen somebody getting a morality-boner over being a vegan. Your four examples are anecdotal, much like mine, but we also see this sort of defensiveness around other topics where the conventional morality has some problems that conventional folks don't conventionally want to grapple with. I like Ian Danskin's work in general, but the way he looks at this in particular has resonated with me: https://www.youtube.com/watch?v=ExEHuNrC8yU https://www.youtube.com/watch?v=ExEHuNrC8yU
