I'm not disagreeing with you! We just need people to make this sort of point thoughtfully, in keeping with the site guidelines. I know that's not always easy when strong feelings are present. (It happens to me too.)

I also don't disagree with you about people's lack of consideration for others, but I think the scope is much too narrow to talk about that as a HN thing or a SV thing or even a national thing. It's present way beyond those levels and may just be a fact of human nature (though fortunately not the only fact).
