I mean this kind of a perfect example of doing the thing where you blow shit up over an extremely pedantic issue which is at best tangentially related to the core ethic, specifically because you view nuance itself as a threat. As far as purity tests dissolving into self parody, I'm not sure there's a better example for veganism.

And I say this as a person who otherwise sympathizes with vegans, but often finds them insufferable. Self awareness is the vaccine to self parody.

I have opinions on a lot of things that don't effect me at all. Palestinian genocide, Uighurs in sweatshops, child labor laws in other states, homeless people being harassed, the socioeconomic shift of Hong Kong losing independent legal rights.

I can respect their freedom to ally themselves to people who wish them direct harm, but I also have the freedom to express my disappointment in them.
