I'm suggesting that it can be valued for pleasure, and it can be valued for procreation. Because both are true (at least in the PIV scenario).

The anti-sex folks are following old, overly simplistic, and ineffective campaigns to "protect people from themselves (via their genitals)". Most of it is well intended but oh so wrong.

Edit: the only problem is the boundaries of power -- wanting to apply religious beliefs to the whole population rather than their particular sect. And I'd wager a fair amount of the conflict over this power is manufactured in order to keep the base riled up.
