I'm sure you all must be aware that to ignore is to be ignorant of, unaware of, or to put it bluntly, to be an ignoramus. To deliberately put oneself in a position of ignorance seems a strange attitude to me.
I've never put anyone on an ignore list. Maybe that's because I intuitively believe that anyone, no matter how cantankerous, stubborn or wrong-headed he may appear to be, may eventually have something useful to say.
As regards the comments of Floyd Davidson in this thread, I see nothing egregiously offensive, nor more insulting than certain comments from others, including Russ. The most inflammatory comment in this thread, in my view, is that from Mezzoduomo on page 1.
