I don't think Santorum does a lot of thinking. I saw something here on DU yesterday or so that said something to the effect of:
"I believe in morality, which is doing what's right, regardless what I'm told - not religion, which is doing what I'm told, regardless what is right" . . .
The patriarchal authoritarian automaton mindset of some extremist religious sects doesn't promote much thought. Obviously. And of course if HIS daughter was raped, you can bet that would be "different".
