"The very act of a man molesting a boy unquestionably involves both same-sex attraction"
Not necessarily, as odd as it may sound. I'm not sure what motivates a non-homosexual man to molest a boy (the only case I know details of involves the man thinking it would hurt a boy less than a girl), but it does happen.
Of course, that doesn't do anything to change the fact that those having same-sex attractions are FAR more likely to molest. The fact that SOME same-sex molestations don't involve definite same-sex attractions gets exaggerated by the "gays are like everyone else" people into "MOST same-sex molestations (etc.)," which is NOT true.
