I repeat my question: did Rick S say that sex is for procreation only?
Did he say it recently?
Was it taken in, or out, of context?
If he said it, said it recently, and said it in context, how do you think that is going to sell in the General Election?
All innocent questions.
Santorum's beliefs are completely in line with Catholic teaching that sexual intercourse has two primary functions: unitive and procreative. It unites the man and woman in their relationship (which includes having fun during the process) while the couple is open to the possibility of conceiving a child. That doesn't mean that you must intend on conceiving a child, only that you are open to it. That's why Natural Family Planning is promoted (works just fine) as no contraception is used.
As far as how his Catholic beliefs will play during the general election, he needs to have a JFK-like moment that his beliefs are his beliefs, and why the "bleep" is everyone obsessed with them when we have an econony teetering on the edge of destruction. If he doesn't do that, he'll be letting the libertine liberal scumbag media define the election.
