It's the culmination of a 40-year campaign to destigmatize adult-child sexuality and create a "site of queer pleasure" for male transvestites and kids.

The drag queen might appear as a comic figure, but he carries an utterly serious message: the deconstruction of sex, the reconstruction of child sexuality, and the subversion of middle-class family life.
The ideology that drives this movement was born in the sex dungeons of San Francisco and incubated in the academy. It is now being transmitted, with official state support, in a number of public libraries and schools across the United States. By excavating the foundations of this ideology and sifting through the literature of its activists, parents and citizens can finally understand the new sexual politics and formulate a strategy for resisting it.
