I think that trump really is a social conservative based on how he lives his life and how his kids turned out. However he does seem to think that legislation of moral views ultimately does more harm then good.
More to the point, social legislation is increasingly becoming moot. The SCOTUS continually steps-in and preempts it. A lot of energy gets wasted for no good purpose.
In all of human history, there has never been an occasion when moral views were not legislated.
There is no choice about them being legislated. (forced by law) The only choice is about which set of morals is going to *GET* enforced by law.
