Update: Jan 6:
Michael Gerson has an op-ed in the Washington Post "Rick Santorum and the return of compassionate conservatism", link here. Gerson talks about the idea that people need stable social institutions (the family) which are easily distracted by hyperindividualism, and defines the concept of "subsidiarity" (a Catholic concept here, but intuitive). The problem is that "subsidiarity" will lead to unequal "personal sacrifices" in an environment that otherwise stresses individual autonomy and equality, taken as far in the abstract as possible. This certainly impacts LGBT people.
On the other hand. AlterNet has a piece "Rick Santorum's 10 most outrageous campaign statements" and they sound like "reasoning" drawn into false metaphors, here.
