The proposed ban attracted national media attention, and several "pro-family" groups seeking to drum up support for the bill have been circulating some troubling stats about gay parents. Among the most striking, stated during a CNN program: children in foster homes with same-sex parents are 11 times as likely to be sexually abused as those with heterosexual parents.

To get on CNN, that number snaked through a twisting path, from a little-noticed Illinois study published by an antigay scientist/activist in a psychological journal, to several conservative Web sites, to, finally, the attention of a Texas activist who presented her misinterpretation of the study on national television, essentially unchallenged. It's a textbook example of how flawed numbers can gain national attention if advocates work hard enough -- especially when there aren't widely-known conflicting estimates.
