Well, technically no, crickets are not vegan.

However... i believe there will be a campaign... brainwashing... that crickets ARE kosher vegan
or something like, saving the planet is more important that veganism. (higher on the scale)

That will be the real mile marker, when we see the TV adverts for Cricket-tism is better than veganism.

Or maybe it will be, enjoy the crickets, or this large bowl of nothing...
