Why do american's think they should decide if women are allowed to have n abortion?:
Americans as a whole do not think this way.  There is much controversy in our country about this issue.  It is currently legal in most (I believe) states to have an abortion, but conservative religious zealots are always trying to change the law.  Obviously, I am pro-women's rights (not pro-abortion and not pro-life, but believe that since it's the woman's responsibility it ultimately needs to be her choice.)
