"Given men's track record (including the current government) I don'T think we have any choice but to make at least 50% of MPs women."
Would you care to give a moments thought as to how you actually might achieve that sound bite?
Imagine the following scenario, Parliament achieves your 50:50 balance, there are two bi-elections, each has a mix of male and female candidates. However the winners are two females. That would tip the balance wouldn't it. So what happens? Are the people of one area told "yes I know you voted for Miss X but Gubbins-On-The-Hill down the road have voted for Miss Y and you've drawn the short straw. Parliament has got to be 50:50, so you're going to get your second choice of Mr X as your MP even though hardly anyone voted for him".
Quite ridiculous, yet the only option if you have a legally binding 50:50 split in Parliament.
And any system that basically says "the only way we're going to get more women into Parliament is to enact laws that demand sex bias" is just a bit demeaning, I'm with Anne Widdicombe on that one.
And then isn't there something very rotten with the concept that "we're going to fight repression and bias by legally enforcing repression and bias".
"BUt yes, more women need to run for election, eithout a doubt."
There I do agree with you.
But there's a difference between encouragement and fiddling with the very basis and make up of our democratically elected Parliament.
