I'm no fan of Clinton but have you maybe considered that there is a glass ceiling? There have been two major party female VP candidates (one mentally challenged, the other several decades ago). There have been no major party female presidential candidates. There are currently only 6 female governors, you'd expect 25. There are currently 20 female senators, you'd expect 50. There are currently 84 female representatives, you'd expect 217.5.
The demographics are even more out of whack for racial and religious minorities. Our government is disproportionately white and male. That really can't be argued though the why certainly could be.
Vote for or against Hillary on the basis of her policies, not gender. However there's no reason to pretend there's not a glass ceiling. The permeability of that ceiling is improving but it's clearly still there.
