Palin posted a photo of her Dec. 8 visit with the Robertson family during her book promotion tour.
Robertson apologized for the remarks in a statement:
I myself am a product of the 60s; I centered my life around sex, drugs and rock and roll until I hit rock bottom and accepted Jesus as my Savior. My mission today is to go forth and tell people about why I follow Christ and also what the Bible teaches, and part of that teaching is that women and men are meant to be together. However, I would never treat anyone with disrespect just because they are different from me. We are all created by the Almighty and like Him, I love all of humanity. We would all be better off if we loved God and loved each other.
