Sex is powerful, wonderful, and deeply spiritual. What God has joined let no man separate. We believe that sex can never be divorced from love and commitment without consequences. And when sex is practiced casually and promiscuously we believe that there are consequences for society at large, beyond those engendered by the mere participants. That speech has the power to change behavior.
Pornography is propaganda for sexual perversion.
Propaganda works, but that never cancels or absolves us of our ability to reason and choose. That you really do reap what you sow. That pornography is nothing more than the crass exploitation of sex for commercial gain. It is a cheap substitute for the real and healthy sex that God wants all married couples to enjoy. That no man, or woman, is an island unto themselves.
