I have also contributed to John's site. I see him as a genuine folklorist. If you don't like it, you don't have to open the thread. I don't like my kids using a lot of swear words, but I can't get over excited about it. Mind you, if they used words like "nigger", "coon" or "wog" (which in reality, they would not dream of doing), then I really would hit the roof.
Most people copulate, defecate and possibly even fellate at some time in their lives. I can't get any more upset than Clinton Hammond does about people using rather more prosaic language to describe these activities.
