Veganazi

A vegan who is almost Nazi-like in his or her belief in veganisn, such that they feel the need to feel enraged by anyone who eats any form of meat, and go on a vegetable-fueled rage about how "meat is murder" and that meat eaters are "disgraceful, uncivilised, barbaric and primal" beings that should have gone extinct around the time of the Neanderthals. They also don't accept that going vegan isn't the best thing that could happen to anyone, and refuses to listen to anyone who says otherwise.
