Laughing at people for being vegetarians is like laughing at people for being gay when it is not like laughing at people for needing mobility devices. But of course oppressed groups are no better than we are. There are, for instance, the PETAmanes, who put up ads showing Black people as no better than animals and, when criticized, indignantly reply that they also think white people are no better than animals. (I’m willing to concede that they’re right about themselves.) And now we have the butthole wars.
