I’d agree that posters of thongs are an utterly unconvincing, if attractive, example of First Amendment rights at play, although why anyone would worry about such advertising is quite beyond me. On the other hand, the idea that government should intervene to support “the norms informally enforced by… religious communities” seems, to the extent that those norms are specifically ‘religious’ in inspiration, both (1) in breach of the separation of church and state and (2) in an age where this country seems to be playing host to increasingly fundamentalist sects, profoundly unwise.
