Sigh. It's the _bad_ feminists that go all superior. True feminism is simply striving for equal opportunities for both sexes.
No, a group of geeky females - who have managed to catch the public eye - just want to get together with other geeky females.
If they opened up these dinners to both sexes, you wouldn't even have more than half (or even a quarter) of those in attendance being female - and when basically the whole point is to have a natter and a gossip and be able to mix in female company (we like that sometimes, just as you lot like nights out with the lads) - it'd be either (a) a bit crap for the men who turn up, or (b) suddenly not very girly an occasion at all.
