It's very difficult if not impossible to reverse this. You can educate people about how awful you believe it is but when you tell a female that the right to have an abortion will be taken away from women who live in America, you can't win.
Say what you will, show pictures of aborted babies as much as you want -- it's still very, very difficult to remove a "right" that people have women have fought for. Now, it's been several generations since 1973. I can't imagine enough people are ready to make this illegal again.
