Because we would be stupid and unwise to think that the RCC, or the Boy Scouts are unique problems if we care about your children and our society.
Even at the height of the RCC pedo problem the rate in the RCC remained lower than public schools, and probably in the public at large.
If you care about protecting children, and understanding this problem, you have to look at it in a realistic way, not just where vibrant headlines and your own biases lead you.
If all you care about is calling groups or people you already don't like pedos (see recent groggy example), than carry on in the same fashion. You will have plenty of company. You will not be understanding this problem, but you will not be lonely.
