This, 100%. For some reason people imagine vegans as an ideologically aligned group rather than a bunch of people making their own varied decisions for their own varied reasons. Then when inconsistencies come up between vegans they’ll decry it all as performative.

Setting a unifying standard for a broad group of people that they’ll never meet and then reacting to the shock of them failing to meet that standard is a common rhetorical tactic in other contexts, no surprises it turns up here too.
