Most Paedophiles are not homosexual in the accepted meaning of the word. Leaving aside the father/daughter, or mother/son proportion which are definitely not a gay issue, the man/boy or woman/girl perpetrators are rarely actively homosexual with adults. They are paedophiles because their sexual orientation is child based.
Most homosexuals are not paedophiles, as their orientation is based on adult members of the same sex.
If you see homosexuals as more likely to indulge in child molestation, it seems to me that this says more about your innate fear of "the different" than about your grasp of the situation.
I once commented to a friend, who happens to be gay, that before I came to know him well, I had dreaded the possibility that he might one day make a pass, and I feared that I might handle the situation badly.
He laughed and said, "Would you make a pass at a gay man?..Of course you wouldn't. So what makes you think I would have any interest in a straight man?...You just ain't my type mate.
IMHO, for the vast majority of gay men, kids just ain't their type. That's the province of paedophiles.
The cockup in this case was in the failure of social services to investigate allegations of abuse. The sexual orientation of the abuser is outwith the parameters of that, and rightly so.
