That a Catholic could reasonably believe that Church teaching should not be the basis for public policy does not seem to have occurred to Feser. There is no contradiction in believing that X is morally wrong, while simultaneously believing that X should be legal. To argue that Catholic politicians are obligated to use their power to implement the Church's moral principles is to argue that America should be a Catholic theocracy, and people who hold such views have no business giving lectures on tyranny and persecution.
