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.
