Could female ual abusers of children be more widespread than we think?

I was abused by two women. I went to a support group for survivors in the 80's. It was an informal drop in kind of thing, not therapy. There were about 50 regulars. I would say of that population, about 10% were directly abused by women and about another 10% had their mothers play an auxillary role, such as watching. At that time the head of the M. Soc. for the Prevention of Cruelty to Children said ual abusers are about 15% female. This phenomenon is kept quiet by the pressure of feminists in our society who push the myth that women can do no wrong.
