It wasn't intended as a comment on anyone's personal worth as a human being, or what they're like in person. I have spent a good amount of time following OpenBSD-related mailing lists, though, and I'd say "polite and collegial" is not the prevailing tone--- hyperbolically trashing other people's work and calling them stupid monkeys is more par for the course. Admittedly, they don't have a monopoly on that; plenty of GNU mailing lists are similar (esp. anything RMS or Ulrich Drepper regularly posts to).
