Isn't it fascinating that some women seem to 'allow' decisions like this to be implimented?
Get 6 single female students to agree on a policy of 'sod that for a game of soldiers'...that's all it would take. At every given opportunity, gathering, lecture, group discussion...whatever.....stand up with a sheet of interesting and relevant notes and start to TALK OVER the male speakers. Just keep doing it, over and over. If you're asked to stop, say you'd prefer not to and keep going. It would cause ructions! Just keep doing it, day after day.
Then whilst the 'think they're important' people are getting together to seek a solution, phone the local press, get them along to the next event that you plan to speak at and tell them you wont be cross if they send their report and photographs to the Daily Mail. Finally, everyone tweet like mad about it.
I'd give it 2 weeks max before the decision was reversed.
