I've posted before what underlies the changes being experienced by the right. That right has inveighed against those components of our population who engage in behaviors considered inimical to societal interests. However, as the population has increased and as that population's exposure to and engagement in those inimical behaviors has increased, many if not most people find that they have family members and friends who engage in those behaviors. Thus, they are reluctant to apply society's constraints to them. When one has a family member who is a homosexual or alcoholic, one's recrimination tends to be mitigated by the familial relationship. Thus, one is unwilling to support a general admonition of such behaviors and, in turn, political parties or movements, or laws that do so.

I think that the Palin kid's pregnancy is a perfect example. Her mother cannot inveigh against against pre-marital sex as vigorously as she did before and support punishments, etc. because now she has one in her own family.

Those of us who are parents may understand this better than those who are not. When someone else's child engages in anti-social behavior we may be willing to see them hung. But when it is our child, that's a different story.
