I don't actually have a problem with people being wrong or not very bright in the comments they make. I have a problem with the arrogance and self-involvement that I feel responding to someone like this — someone who has literally signed up to HN so that they could share a few paragraphs about their life — represents. So if you can do a better job of making the problem with that clear to people who might otherwise make such a mistake, then that would be even better.
