Please don't post in the flamewar style to HN. Internet threads can't handle denunciatory rhetoric without collapsing. It's the way the medium works, and we have to consciously compensate for it, if we're going to keep curious conversation going here.
I think flamewar is for when people will have polarized views on a particular topic and the poster posts only to bring the people to fight each other.
My post is what I think a necessary reminder in a topic that I honestly don't think is very polarizing. It just needs to be repeated, over, and over again. The same way it gets taught to kids at school so they teach it to their kids, and so on.
Because it is important.
Think about this: if something is taught to kids at school, how can you justify objecting to it on HN (I mean unless it is a topic that is obviously incorrectly taught, which I suppose this is not one of them)?
I doubt that you would want other commenters to drill you like a schoolchild, but even if I'm wrong about that, please don't do it to others on this site. We're trying for entirely the opposite sort of discussion. Basically, if it's predictable, it is off topic here.
