This point can't be made often enough. I can't say that I think there are "too many" (or even "an increasing number") of posts on HN that seem to assume that everyone here has precisely the same set of (often extreme) values, but these kinds of presumptuous, somewhat self-righteous postings do pop up from time to time, and this is precisely the reaction I always have. The definition of "self-respecting hacker" does, after all, probably very between self-respecting hackers.
