Ah, that makes more sense - I could only see the two comments you linked to. I gathered there were objections to the panel being all white males, but sadly that's hardly unusual.
As a random aside, since when is Bill Bailey a scientist? He is a feminist though, so I'm surprised he's continued to be associated with this event if what you say is true about them slagging off women on their website.
I'm a scientist; a molecular biologist/virologist, and we're pretty much a 50/50 gender split at the bench. There are still more male group leaders and in management, but I hope that's a relic of the previous generation and when my cohort rise to the top the genders will be far more equally distributed. My point though, is that the "women don't do science" is certainly not true in the Life Sciences; we're probably getting more female new graduates coming into the lab than males. But more work definitely needs doing in the more "manly" sciences like maths, physics and engineering.
At the end of the day, this organisation can't be all that groundbreaking if they can't persuade a single non-white-male to sit on their panel, and then resort to insulting people who point this out. They'll have lost a lot of credibility; I certainly won't ever take them seriously.
