Yet another sweeping statement without documentation.
How do you explain the well-proven fact that while male homosexuals make up something likely less than 3% of the overall population they account for somewhere in the range of 30-40% of all convicted pedophiles?
See (as but one example):
Homosexuality and Child Sexual Abuse
Rather than cite an obviously long list of female child killers, I'd contend that, based upon the vastly different standards of justice which the sexes are respectively held to, most gender based crime statistics are rendered essentially meaningless.
