On gender balance.
There's been a lot of hoohah on the blogosphere about all-women shortlists. (Against, mostly Nats like Jeff and Mr Macnumpty, also Political Dissuasion: for, Labour voices like Kez and Yousuf).
Without wishing to sound like a Liberal, I think they're both right. All-women shortlists are indeed a crude and anti-egalitarian way to try and build gender equality.
However, I can't stomach the complacency, the desire of some to stick their fingers in their ears when others point out that Parliament is about 35% female, down from almost 40% in 2003.
The position in our local authorities is even worse, and declining. Less than 22% of Scottish councillors elected in 2007 were female, marginally down on 2003, and even further down on 1999 (pdf).
The Green approach is different - our constitution requires that at least 50% of our candidates for winnable seats are female. There's an exemption for sitting MSPs, which is one of the reasons both my MSP employers are male, true, but at the Council level we're exactly 50/50.
Looking beyond the obviously winnable seats, we balance there too, but not as tightly. 40% of all candidates, minimum, must be female, and 40%, minimum, must be male.
Now, this certainly makes it more complex to select candidates, as Green activists will tell you, but it can't be seen as discriminating against either gender, nor is it "positive discrimination". Indeed, in one branch there would have been an under-representation of men without this mechanism.
It's not a magic bullet. It should only be a transitional mechanism, although that transition might be lengthy. It doesn't cover other sorts of equalities, from transgender to race and class.
This principle has, however, encouraged more women to put themselves forward, and through it we've selected more good women to fight and win elections, women who continue to grow in those roles and who inspire more good candidates to come forward each time we select.
I know it's also easier for us than it is for other parties, given our focus on PR elections like the Holyrood lists and local authority contests. But couldn't other parties try something that's not one of the two failed models the blogosphere has adopted, just as the other parties have? (Malc is an honourable exception here)
It's a classic false opposition. Parties shouldn't be excluding men, but nor should selection meetings where the loudest and deepest voice wins be the norm.
