This may sound callous but when The Santorums chose to have unprotected sex at that age a resulting pregnancy has a 1 in 10 chance of a genetic defect (like Bella has). This did not have to be with a little common sense and birth control. Actions have consequences. I fell terribly for Bella as she is tormented by her body. The Santorums of course will not think of it as that. I do.
