Well I've just watched one of those Portillo railway episodes, one in which he visited Manchester. There was a detail of three women, suffragettes, who walked into an art gallery and attacked the glass fronts of several paintings (some of which were those of pre-raphaelite tossers) with little toffee hammers. No messing about talking about it, no worries about public condemnation. And guess what. Eventually, women got the vote. Learn from history, or, as the yanks would say, go figure...
