I just noticed your conclusion is flawed in that you assume that the overall homosexual 34% comprised of males and females is distributed the same as the incidence of male and female sexual abuse of foster or subsidized-adoptive children which is incidently not stated as homosexual in nature (could be a composite).
No, I didn't make that assumption. Not making that assumption is what my analysis was all about. Note that F and M are not the numbers of male and female foster parents, but the numbers of acts of sexual abuse committed by each of these groups. So the equation you question is correct, based on the figures given in the article.
Yup -now that I read it again, you are right. So the conclusions will anger both homosexual activists and radical feminists...
