Most Catholics you have met are immaterial, because the OP distinctly mentioned postliberalism. If you want to bring up Catholics here, then the Catholics who would bother to identify with postliberalism, which is after all a stance of political philosophy, are largely those Catholics of a philosophical bent, and that is why one hears a lot of Aristotle in defense of their political and social models. I have my own disagreements with Catholics because I am not sympathetic to many claims of Aristotelianism, but on HN facts matter.
" Most Catholics you have met are immaterial " Most Catholics just suck what they learned during child hood. They are postliberal as they wish a Catholic society which is hence not liberal. Arguing with Aristoteles is just plain sane washing as the bible is intellectuelly very thin.
