This is apparently a new phrase gaining traction, which I should probably consider embracing in preference to "Postliberal."
It has significant PR advantages over the approaches I have been using. However, I suspect it is not quite honest in my case. I might culturally feel at home with liberals, but I long ago rejected not only their rude and dishonest argumentation, but some of their core principles as well. While I am neither conservative nor libertarian, I agree with those from first principles at least as much as I do progs. Denying that for the sake of a more successful sales pitch, though perhaps politically defensible, does not seem morally defensible to me.
It might, however, apply quite accurately to any number of you, and I admire its style.
Interestingly, there is a natural counterpart to that. Dissident conservative might apply quite nicely to many of my friends and relatives.
