And let's take his stance on gay marriage - it destroys family values, yeah. Nevermind that divorce is the number one destroyer of families. We don't see him banning divorces - oh, no. Anyone with any wit whatsoever can see that the entire reason men and women can no longer be bothered to stick it out, ride out the bad times, work on their problems, and honor their promises to each other is because them unholy fags have cheapened the concept of marriage, right? Right! That's morality in action for you, right there! A shining example of it, in fact.
Marriage is the leading cause of divorce in this country. 
Marriage originally was 1-  A way to increase survivability of the family unit; and later became 2- A way for men to exert control over women.
In the modern era where natural selection is an ever decreasing part of the life equasion and where the state seems determined to develop children to it's own standards, the institution of marriage is superfluous.
I find it the height of arrogance to expect to be everything a partner would need for their development for the rest of our lives.  Add that to the reality that I am not the same person from one day to the next, much less one year to the next, it would be unfair to expect another individual to grow in the same ways that I do.
I like the Heinlein model of family where groups of people live communally with understanding and love, each performing according to their strengths, but then, since there are people involved, with all their attendant feelings and tendencies to get those feelings hurt, I really don't know about the practicality of that setup.
Also, I find the inundation of america's children with the Disney Ideal of a One True Love that will ride in and sweep the Little Princess off her feet to his castle to Live Happily Ever After to be a deplorable practice.  Brainwashing children to expect an Ideal results in disappointment.  People are fallible, mistakes inevitable, and it is unfair of the entertainment industry to offer any other version of reality.
As far as the main concepts of the post go, I view morality as a function of the indoctrination of the general viewpoints of the larger society a person grows up in, as that code relates to the intellectual revision applied due to personal experience and expedience of the moment/circumstance in which applied.  The most important thing though, in my opinion, is to explore yourself, and be comfortable with what you find, or change.  But above all, the standards must be your own, not blind obedience to what everyone else seems to expect.
