As the question of Westminster keeps being tossed up... The selection of MPs is a complicated business. Deselecting a sitting MP is not an easy thing to do as the deselection (at the next general election) of Tim Yeo recently has proved, and he hasn't been deselected in favour of a woman, he's been deselected because he's useless.
Only one party - Labour - run women-only shortlists. The Conservatives, for instance do not, despite women Conservative MPs being heavily outnumbered 48 female to 256 male. *
Men are not being discouraged to become teachers, they obviously don't want to join the profession, otherwise, what's stopping them? Blaming women in general, and feminists in particular, is both erroneous and ridiculous.
