The homosexual lobby say that they are 'born' with their affliction
and the link provided by Steve Morson says that abusers of pre-adolescent and adolescent males are 'retarded male heterosexuals' and not homosexuals retarded or otherwise.
For both propositions to be true, the 'normal' heterosexual must have from day one of its birth only been attracted to adult males of 18 years old, so whilst the 'normal' heterosexual male developed a crush on a fellow female pupil, the 'normal' heterosexual male only developed crushes on his adult male childs without going through any phase of being attracted to males of his own age. Steve Morson's link would have you believe that those male adolescents who fancied fellow male pupils but not adult male teachers either grew up to became 'normal' heterosexuals as adults attracted to adult women or remained as adults still attracted to young adolescent males.
Has the smell of BS to me rather than the ring of truth.
