Eating disorders is one of them.
If you watched my recent video (see below), you will know I launched into a fit of rage over a young man named Kenneth Tong, who has a Twitter account (and I believe a Facebook page, and soon-to-launch website) endorsing "managed" anorexia. I was alerted to this man from a Twitter follower of mine, who indicated that I should sign a "Twitition" (get it? Like a petition, only for Twitter) to kick this man off Twitter. His view is that women who are not a size zero, ARE a zero. And he encourages women to skip meals in order to achieve this.
