I have been searching before but sadly could not find it. I'll keep searching.

It's not the post I have been thinking of, but there is a line there

"[...] but you should wonder: when more women enter a field, it means less men did, and if the men stopped going there, where did they go? Why did they leave? I assume they aren't home with the kids, right?
I don't want to be cynical, but boy oh boy is it hard not to observe that at the very moment in our history when we have the most women in the Senate, Congress is perceived to be pathetic, bickering, easily manipulated and powerless [..] if some field keeps the trappings of power but loses actual power, women enter it in droves and men abandon it like the Roanoke Colony. Again we must ask the question: if power seeking men aren't running for Senate, where did they go?"
