I would instill a greater understanding of the world's religions outside of Christianity.
I would want every American to have a basic awareness that Christianity was just one of many different faiths practiced around the world, and that in fact Christians represent a minority of the world's population. And that adherents of those religions were also here in the States. And that the people who practice those religions should not have to live under policies formed from the framework of particularly Christian morality.
Furthermore, perhaps if they understood that all Abrahamic religions involve the same deity, and that they share many tenets, perhaps that would take some of the wind out of Fox News' sails.
And finally, maybe they would stop confusing Sikh's with Muslims.
