It probably won't help you feel better, but it bears reminding that there is a very strong religious component in play here. People don't vote against abortion because they rationally attend the argument. They do it because "god said so". This is the real hurdle you'll need to overcome in order to maintain women's rights. You're not fighting men or conservative women, you're countering the word of god. It helps to picture Americans as religious fundamentalists. Focus on solutions to that problem and you'll have higher success than simply attaching facts to legislation.
