Miller
Obscene material is proscribed in this way [by the Miller test:] it appeals to the prurient interest [and] it's offensive. Basically, it's "It excites me; and I hate it."
I want to amend Zittrain's description of Miller to include the third prong (the material has no serious scientific, literary, artistic, or political value). So:
It excites me; and I hate it; and it sucks.
