That is an outstanding analysis, but I think it lacks one piece. The selfishness is not just the use of things for pleasure, but the use of people for pleasure. Using a man or woman for sexual gratification, without any intent to form a lasting relationship, reduces that man or woman to a mere animal - similar to enslaving them. If they proclaim to like being so reduced - as even one FReeper has claimed - we have done even worse than reducing them to the status of a beast.
We have taught them to accept it.
Shalom.
Possibly the most insidious effect of pornography and purposefully non-procreative sex is consistently overlooked at our peril though it provides an excellent explanation as to why Hollywood agit-prop artists drape the likes of Larry Flynt in an American flag as an icon of dumbed down "Free Speech".
Both porn and contraception destroy man's natural sovereignty over himself and reduce him to a Thing to be Manipulated.
Is it any wonder our government is only too interested in our being consistently conditioned thus?
Best regards.
