I won't dispute that Western Christianity (i.e. Catholicism and its Protestant offshoots) has had a profound influence on Western culture, but it's a continuation of a phenomenon that predates Christianity.
No argument there, agreed.
My point, (which is almost impossible to make in any environment dominated by the theist vs. atheist food fight) is only that Catholicism dominated western culture to an incredible degree for a very long time.
I'm not attempting to assert the Catholics are always right, or that they invented their perspectives, or give credit for anything other than it was primarily them who pounded these ideas in to the minds of the modern western world.
It's as if some insurance company ran ads on our TV all day every day for a thousand years. The product might suck, it might not even be their product, but they would still be very influential.
But, because I said the word "Catholic" in there somewhere this must somehow be found to be totally wrong, Wrong, WRONG!!!
