It must be noted that pedophila is something that is viewed as wrong and unaccetable NOW and in THIS society, but that was not always the case and still isn't in some places.
And while I agree there is a big difference between homosexuality and pedophila, we must acknowledge that the difference is one of morals more than anything else and that is even more the case if it is proven that both are hardwired ie: a person is born that way.
Of course that brings us to the issue of how to view both behaviours since both are techinally "deviant" ( other than the norm).
The key issue is one of consent and appropriate age and development and in that regard, we get a broader range based on societies and cultures ( and example if the different age of consent all over the world and even within a specific country at times).
