Do you know why?

Why?
I have been asking this question for weeks now. Why are women's reproductive rights under siege? Our access to a safe, legal abortion is being threatened. More hurdles than ever are placed before a woman that is seeking an abortion—a medical procedure that we legally have a right to receive. Some politicians in Virginia—mostly men—want a law that requires a woman to have a vaginal ultrasound--from personal experience I can attest that this is very invasive--before she has an abortion. And I thought Republicans wanted the government out of our lives.
Why do so many want to roll back access to preventive healthcare for women? Legislative ideas put forth would deny many women access to affordable birth control--and just so everyone knows, birth control isn't always used to simply prevent pregnancy. There are a host of reproductive disorders that can be controlled with the use of hormone-based contraceptives. But really, what is the problem with a woman preventing pregnancy?

What motive is there to rip away all the gains we've made in healthcare, family planning, and even the work force (no birth control means a lot more pregnant, stay-at-home moms)? Who benefits from such draconian measures?
