Women voting raises a slew of issues like women's rights, extreme tolerance of women, biased sexual harrassment laws, and abortion into the picture, and truly, America would be a better place if feminists had no power.
I agree about feminists, but most women are not really feminists, at least not in the extreme sense. Some men are also male chauvinists, so it's indefensible to argue that voting rights should be taken away from an entire gender due to feminists, much as I can't stand them. And don't forget that there are plenty of mentally castrated men who support feminists.
Even the feminists never went so far as to argue that men should be denied voting rights because of male chauvinism. Feminists are effectively female chauvinists, and they need to be defeated in the war of ideas, not be restricting voting.
