Women aren't launching tech/web/software companies at twice the rate of men, so that's irrelevant. Few other fields do VC the way tech/web/software does.
Correlation, causation, everybody's heard that old saw. I certainly didn't say what you claim I said. What I said was: Few other fields do VC the way this one does. By which I mean, most fields don't do VC.

VC is almost purely a tech/bio/med thing. Most small businesses - which is what startups are, by the way - take loans. That's how it usually works.
