I started commenting on people's attacks on me because these things always end up - at least, any time there is a chance to make me look bad - in f_w or the like, where they are read by people who know nothing about me except what they read there. Then they become ortodoxy. I wanted my point of view to be on record, because if I do not record it, no-one else will, and, as long as wankers wank, the opposition viewpoint will go by default.
