Very few of the people who wrote to me are of conservative political orientation. Rather, a main thread in the missives is people left-of-center wondering why, suddenly, to be anything but radical is to be treated as a retrograde heretic. Thus the issue is not the age-old one of left against right, but what one letter writer calls the “circular firing squad” of the left: It is now no longer “Why aren’t you on the left?” but “How dare you not be as left as we are.”
This is the most revealing quote for me as a fellow left-of-centre person disgusted by this behaviour that overwhelmingly comes from our side.
It's shocking to me that after a few years of this stuff there are still people on the left - including regularly on this site - in denial.
