Thanks both of you (boudewijn and Cyberax) for setting an example!
As an aside -- Cyberax seems to be of Russian origin and boudewijn, I assume, is of Dutch or Flemish origin. The Dutch are among the most polite people I've met. The Russians I know are polite to me, but I've seen Russians talking to one another (in English, because others were present), and the aggression is staggering -- it seems like any moment they will come to blows. Yet there's nothing personal in it -- it's just a vigorous argument, Russian-style. I suspect a lot of personality conflicts, especially online, are merely cultural issues and could be resolved if the people involved met in real life (or, as in this case, made an extra effort to listen to each other).
Apologies if the stereotyping was incorrect in this case.
