I suggest you go and read the Constitution, The part about "to provide for the common defense" and the part to "insure domestic tranquility", "promote the general welfare" and so on and so forth. No it wasn't written with you in mind. But society in general.
So just to clarify, Cacique, should there or shouldn't there be laws against contraception, or against non-procreational sex acts between married couples? That's all I really care about. If you just disapprove, I couldn't care less.
