I've seen some very interesting theory from an anti-feminist writer who goes by the name girlwriteswhat (she's female herself) on some of the outgrowths of giving women the vote.
Now, keep in mind she doesn't say that women SHOULDN'T have the right to vote, and neither do I. It's just interesting some of the theory she laid out on it's impacts.
To sum it up quickly, the idea is that women are genetically programmed by natural selection to always look for a bigger, better male provider. Once the government got into the business of being a provider, no individual man could ever compete with it. In effect, the government triggers as a mate/provider to the instinctual female brain, and being able to vote to make it a better provider ensured the downfall of the family... which is why divorce rates are so high, and if women can get the government to force the men who provided the genetic material to create children to provide financial support for 18 or 21 years, or make men in GENERAL provide that financial support via taxation, redistribution, etc... it effectively eliminates the need to keep an individual man in her life.
And being raised by a single-mother has been shown to lead to just about every societal ill imaginable increasing. Ironically, though our system HEAVILY favors giving custody to the mother, being raised by a single-FATHER has been shown to produce healthier, better adjusted children of both genders on every possible measure.
Perhaps this ties in with the old "spare the rod, spoil the child" thing. Women's instinct is typically to nurture, nurture, nurture. Men are a little more practical and perhaps harsh, to a degree. It feels very nice in the short term to give your kid everything they want, it takes strength to not do this. To instill discipline, etc.
The problem is, if you give your child everything they want, treat them like a friend more than a child, you see the results all around you in our society today. You end up with ungrounded, airy, flaky children who are the same way as adults... who aren't practical, aren't responsible, who feel entitled, who linger in their parents home much later into life, who are less suited to start their own families, and the cycle perpetuates itself.
Think of all the little brats you see these days who don't mind their parents at all, who emotionally manipulate their parents, and the parents who freak out about every possible allergy, like the woman recently who wanted her kid's school to cut down all the oak trees because they had acorns on them :|
Endless babying of children, refusing to make them GROW UP. More and more single-mothers... cycle perpetuates, cycle gets worse.
Our society is a reflection of who has the power, men used to have the political power just about exclusively, and the society reflected it. If society and government used to be analogous to a father, it's increasingly becoming analogous to a mother. The problem is that men are programmed to protect women, give them what they want, and so once women had the vote, the result was nearly inevitable. Government and society were slowly (kinda quickly really) reformed in the image of a woman, or perhaps a woman's desire, the ideal, ultimate provider.
A father tends to expect growth, self-sufficiency, standing on your own two feet. Society used to expect likewise. Now? Not so much.
Just food for thought. Not saying I agree with all of this, but this is basically the ideas I've seen laid out, and there may be some merit to it.
I am by no means saying women shouldn't have the right to vote, but I do think the feminist movement was too extreme, and got too much of what it wanted. I think society should've been more cautious in the changes it undertook, and tempered them more with caution and restraint. I think men should be more inclined to think of themselves as a group, like women do, and stand up for their rights, like women do. Rights of fatherhood, etc.
Here's a good video from girlwriteswhat that touches on some of this, really worth your time:
