Benevolent Creator God?

[The Architect Of Fate]

I think you can use logic here.

Without any reliable data, logic won't suffice here.

  The proportion of gay priests is declining; 

We don't actually know that 

 the rate of new cases of boy molestation has declined during the same time period.  

We don't actually know that and I already gave two far more reasonable explanations for the same drop which are reinforced by data on the nature of pedophilia.

If you say it's a mere coincidence, do you have evidence it is?

I never claimed it was a mere coincidence. You by contrast have banked your hypothesis on a mere correlation with foundations that have not been quantified in any meaningful way.
