How many of these Protestant clergy were protected from the consequences of their sexual depravity by their Church, as was the case with quite a few Catholic ones?
Therein lies the problem. The Church itself became party to the sin when it concealed the existence of it.
Hopefully, that concealing is in the past, and those clergy prone to such behavior have been removed from current or future postions of trust and authority within the Church.
I've long felt that your seminaries were deliberately targeted and infiltrated by radical homosexuals, personally. Root them all out, they're tares.
And, that's not just an admonition for Catholics alone. We've got our own problems, especially with the well known mainline denominations, ourselves. This may sound odd to you, but at least we have alternatives. There are advantages to decentralization.
The fact that the incidence of occurrence is 5X to 10X higher among the Protestant Clergy and not widely known is evidentiary. The major difference is that the Catholic Church self insures and most Protestant churches maintain expensive misconduct insurance policies with strict confidentiality provisions.
