Pedophiles are rarely interested in a child's sexual orientation; they are interested in satisfying their cravings in an illegal and socially unacceptable manner.
Since there are ever so many more heterosexuals in the world than there are homosexuals, most child molestation is perpetrated by heterosexuals; also most is perpetrated by men.  So, you are suggesting that heterosexual men are trying to change the sexual orientation of children?
Another deep breath might be in order.
It would be most worthwhile to read the following article by a research psychologist at the University of California:  http://psychology.ucdavis.edu/rainbow/html/facts_molestation.html.
Please read it carefully.  It addresses all of your concerns.
