I see the photos of children at Pride marches, being forced to witness BDSM paraphernalia, at Drag Queen Storytimes etc, and it's all an exercise in desensitisation, pushing back the boundaries of what is acceptable for children to witness and participate in.
This seems to be what queer theory is all about. From the article:
Feminists have attempted to develop the cultural norm that rape is bad and that children cannot consent to sexual activity. These activities — rape and child sexual abuse — become reframed in postmodernism, and therefore queer theory, as repressed and a transgression of boundaries which is thus challenging power and helping to liberate the individual.
What seems to be happening, and why feminists are accused of being regressive and siding with religious groups and right-wingers, is that according to this theory, everything that transgresses boundaries is 'progressive' and therefore good. Anyone who argues for the status quo is 'regressive' and therefore bad.
