i would choose a million mosquitoes in my bedroom over a below averagely annoying human

i tell them i would kill a thousand humans and just stare at them while they wait for me to finish the sentence that never comes

And i think answers like this are maybe too concerned with theoretic purity and maintaining a certain label. Do you do what you do so you can call yourself a vegan or do you do it for moral / practical reasons? Personally I would be too disgusted to consume it even though I'm extra agitated when I see it go to waste. A living being created to suffer and die for an abominable purpose and then not even used for that purpose. It's like a mockery and just takes the complete lack of respect for life they have to a higher level. In my mind at least.

Anyway, my point is that an understanding of what veganism is and choosing to be part of it won't cause someone to not see corpses as food. Rather I'd say it's the other way around if anything. One doesn't see corpses as food thus decides to become vegan. But of course that shift in perspective doesn't really occur in some or even most people that go vegan. I mean most of them still like the taste and texture of corpses thus the booming replacement market. So it's more like they're forcing themselves to be vegan. Repressing their urges though the urge is still present. I mean sometimes it can evolve gradually. But as we know most people ''quit veganism''. You can't really consciously decide to not crave something. You can only decide whether to act on that craving or not. Anyway, the way i see it, from a purely pragmatic and utilitarian standpoint, I don't necessarily see his behavior as a problem as it's not actually contributing to the industry to eat what would go to waste. Do i think he can call himself a vegan? Probably not, but I don't really care honestly. It's just a label. What really matters is the consequences of one's actions. Which in his case don't seem to be negative. It's not like it affects the movement in any way either.

That said idk how comfortable i would be with a person like that in the movement and how much i would trust their conviction. So I do sort of agree with you as well. Just wanted to share my thoughts i hope you don't mind. As for your final point, it's exactly why the term vegan itself has soured on me as I feel it's an entirely different ''species'' of an ideology. The distance between what passes for vegan and actually being into liberation is quite large imo.
