I fear I approach the edge on occasion. Still I would say it to your face if I find non depreciating humour in something.

There is always a chance something may be taken the wrong way or a person may have too thin a skin is the risk of this I know.

By and large I believe in live and let live. If I found a compulsion to launch a personal attack I would not do it. I have absolutely no desire to upset anyone. What does amaze me is that so many people of such diverse backgrounds can in general communicate and get along as well as they do on this site. I have not missed that on some sites it is otherwise.
