xishi, I should clarify that I'm not just addressing you here. I don't know if you're judgemental about others, and if so, how much.
Hell, I know I do it sometimes. I get mad when I see someone shop at WalMart or drive to work alone in a Hummer or something. I have to remind myself sometimes, too, that you cannot judge someone quickly, based on just a little information about them like that. I think what set me off more, in fact, was maybe the OP, characterizing certain types of vanity as more egregious than others. What immediately came to mind for me is our own horribly vain LadyShea, who has big purchased hooters and wears makeup and furs and sashays around the place inciting lust into the hearts of men alla damned time. And who subjected herself to major surgery in order to give one of her very limited supply of life-sustaining organs to an acquaintance, thus saving his life. I mean, I still hate what guts she has left for being all hot and having the big hooters and all, but I can't pretend I have any moral grounds for that. The closest I get to giving away parts of my body is when I clip my toenails in the living room and leave them lying around in the carpet to get stuck in my boyfriend's socks. (I do what I can.)
I think what you're doing is good. It's an ethical decision, and one I think is worthwhile. I also think
Dr. Temple Grandin has made an ethical decision, and that her contribution is worthwhile. She's the autistic professor down the road there (I'm pointing north from my house) at CSU, who designs calming slaughterhouses and other facilities to minimize the stress and trauma to livestock in factory farms. She works inside the industry itself, but she does it in a way that profoundly mitigates the cruelty involved.
The world needs both of you. The world needs that big nasty tart LadyShea with her bling and her generalized trollopery. Just because I am so gonna kick her ass doesn't mean I am justified in doing so.
(I am ass-u-me-ing that LadyShea knows I'm only picking on her because I love her.)
