To Vote, Abortion, work discrimination (still going on though). I would get a book and read about it verses going to yahoo answers. The jist of the 70's movement was for more autonomy and control over there bodies and Independence, it fell in a little with Roe v Wade. There was stigma's such as a woman was no good if she had premarital sex (the feminist movement has helped a tremendous amount of guys to get laid by the way). Women were getting treated like second class citizens and just got tired of it. Things like couldn't open a bank account without her husbands permission, or charge a big ticket item without permission. Also, if they were a single women then they were really screwed. I recommend reading about it verses listening to uneducated people rant their biased opinions and hatred towards women.What were the major changes in women's lived experience from 1900 to 2000?
