Sanger was not that unusual for her time and most of us who support programs like Planned Parenthood have zero attachment to Sanger(or we only knew of the sanitized version of her life).  

Now if you are making an ideological connection, take some time to learn a bit about the venerated icon Ayn Rand and her support of abortion as well as well as eugenics.     I personally don't hold Republicans or Democrats beholden to trends of past era's, the world has changed.   Maybe conservatism tends to hold onto what they consider base values longer?    

Do you agree or disagree that Liberals trend toward progressive/adaptive moral structures and Conservatives to think their values are Holly, literally written in stone, and therefor eternal and unchangeable?   As a spiritual person and Christian, I think there is a real problem between the lesson's of Jesus and the rules of the church.     Humans have used religious* justification for some pretty despicable behaviors. *NOT just Christian.
