When I was at the Poly. about 40 (ouch!) years ago, I was friends with a couple of radical feminist lesbians. It was the eighties. Anyway, one of them decided to do a dissertation on pornography, and both decided to go into the Private Shop. They started loudly asking questions of the bloke behind the counter about his exploitation of women &c.. All the punters scattered, and the owner shouted "GET OUT OF MY SHOP!" and started chucking whatever he could lay his hands on, mags, dildos, the lot at them until they left.
