Actually - I've never understood your sentiments, or at least the need to say, "I don't support these people". I actually feel like I do support the people in your listed cases - dark humor has a welcome place in our society - if only to make light of the inevitability of our own impending death.
If you make a good joke of a recent killing - I'll admit that I'll probably get a laugh out of it. I'm not ashamed at all of this. I'm betting a lot of the HN community feels the same way. Will they admit that? That - I'm not sure of.
I am certainly willing to admit that I enjoy dark humor. But then again I am also willing to out myself as a regular 4chan user.
In my opinion this form of dark humor/ridiculing is even necessary. It keeps society "sane", as it counter balances those sacred cows, and brings more relativism into the perspective.
