Oh please. Not too long ago in Florida a Baptist preacher was arrested in a sting when he went to meet a young boy he met on the internet, but instead the cops were waiting. And somewhere else in the south another couple of Baptist "holy men" were convicted of abusing young girls and are now in jail for a long, long time. And in another incident a Baptist minister was arrested when his wife found thousands of the most vile child porn images on his computer. So that's three incidents I took off the top of my head and I bet if I did an internet search I would be here for an hour typing about them. Face it, while you would like to think so, you people are no better than us - the Catholic Church is just the whipping boy of Christianity.
As for Mr. Gerhards ministry not being soiled, how do you know? Most likely such evil things are going on and the fact that his adherants are so small in number, no one has heard about the serious problems that exist. Don't worry, if he and his fellow adherants are humans you can take my word for it, they have the same serious problems any other group of people have in the realm of sex and morals.
