I've been watching this issue with the Thinspo thing, the pro-anorexia pictures, and the like that's been covered on Shopping Cart Disco and NWN this week with interest. I've suffered with eating disorders probably for most of my life, since elementary school really, and I did wonder when the pro-ana/mia groups would hit SL. Because believe it or not, there are so many people out there that embrace their eating disorders and are completely for it. I am very much not one of those people. [I also didn't do my disorders right, because I never got thin!]
But, this whole thing reminded me of some pictures I took last month for the Free Speerit crying skins contest. I ended up not entering because I wasn't all that interested in entering, but I did LOVE the skins and wanted to take pictures. When I first saw the skins, I thought "Ooh, crying pissed off cheerleader!" But later that evening I saw a blog on an exercise outfit and my mind went to "Ooh, crying model." Here are the pictures I took.
It's easy to come into SL with a dislike of your body and wave your wand and poof, you're perfect. But look at it for what it is. You have a lovely avatar. But the person behind the avatar is more important. If you're unhappy with your body, in the real world, please please please don't hurt yourself trying to change. You can't take skinny with you in the end.
