Ill give the OP a pass because he's 15 and so clearly doesnt have the experience to really understand. Its possible he's asking a genuine question and not trolliing.
But dear OP - women are woefully underrepresented at senior political positions and in the executive suites in corporations. They earn 79cents for every dollar a man makes. They are still not guaranteed equal protection under the constitution.
When old white republican politicians are passing leglislation on womens health - without actually talking to any women, its pretty clear there is a long way to go before they reach true social equality. The Equal rights amendment still has not passed -http://en.wikipedia.org/wiki/Equal_Rights_Amendment - primarily because congress is full of rich old white men who are more interested in protecting their privilege and are generally threatened by the notion of true equality.
Spend more time talking to women, gays, other ethnic and religious groups. In fact do it as much as you can. Its the only way you'll understand them. Then one day you will laugh at the naievite of your post. On the other hand - if you don't reach out and learn from people who are different from what youve experienced up to now, then you run the risk of growing up into an old bigoted republican who is afraid of everthing.
Now go ask your mom the same question you asked here. See if she will make it a serious discussion for you . You'll learn a lot about the extra bullshit your mom had to put up with in her life, just because shes a woman.
