I see the statement "Life, liberty and the pursuit of happiness" is to complex an issue for you.
You cannot see at all, blinded by your desire to pervert nature and truth.
The birds and bees, or mammalian reproductive biology, is too complex an issue for you... so is the natural law.
You are not at liberty in life to do as you please in regard to natural law or the laws of man (i.e., the U.S. Constitution, of which, you haven't a shred of a clue). We have the right to restrict your pursuit of happiness, as it may infringe upon ours.
Furthermore, preternatural human pursuits cannot be reconciled with the natural law. Babies are not made in those fashions and the laws of man recognize this in most civilized places of the world.
If not, then the law means nothing and I can freely enforce my will and take my turn upon you as your king.
