He may style himself as a "liberal in the classical sense of the word", but his behavior is pretty illiberal in the old sense of the word, e.g. see Tangurena's comment on his dedication to open discourse or rather lack thereof.
He also has too many fixations that are characteristic of the Left/new style liberals for me to take that self-characterization very seriously.
(Disclaimer: I never read the comment threads on LGF, only his postings. The threads I saw were dreadful to me.)
