I don't recon him to be a fool, he's certainly aware of that it's not a necessity in international discussions - but personally I find it great that he's pulling through with his personal style, and he has every right esp. at his age as he has pointed out a lot of times
For me, it's very nice to have such a diverse community and if there is something to be understandingly annoyed about, it's certainly not members being *too* polite. You might want to try polite next time and could try to send him your suggestion as a personal message and not in public?
+1 - surapon rocks, and he can call me whatever he wants. Great posts and a very positive attitude. Keep doing it your way, surapon!
