Someone once asked (I think) Ruth Bader Ginsburg how many women had to be on the SCOTUS in order for it to not be biased towards men. Her answer was "All nine of them. After all, it's been all nine men before and no one thought that was special"
I am, of course, quite heavily paraphrasing.
But then otherwise we would have a year +0 and a year -0. You really want that on your conscience?
