I don't know... there are people who constantly flap their mouths, don't care who they hurt, and expect people to respond with "oh my gosh, you are just SOOOO wonderful" to every word that comes out of their mouth. I mean, we have ALL put our selves in the position of being a target for this stuff, as well as criticzing it. What I find offensive is when it targets
a) Those who can't help it, are in other words "naturals" or for other reasons they can't choose can't think clearly
b) when the results are tragic. Here I can think all sorts of things about the person's smarts, but laughing about it makes my stomach turn. This can be stupidity on an individual or national level.

As a side note, I think the person who gets my cruelest comments is myself. Knowing myself is not what I would recommend. I'm always smarter than myself and always ready to crawl over myself to boost my self esteem, now does that sound coherent? No. But since when has that mattered?
Anyhoo, interesting thread. Huggs
