In my opinion there is no need for anyone to apologise, the content was erudite, usually polite and interesting.
I won’t debate guns with LB because he knows much more about them than I do; I gave up debating US foreign policy with him because he has had a career in “plausible denial” and further debate gives him an excuse to write stuff that some of the rednecks here want to read. Does not mean I do not enjoy many of his posts, though.
