This was just one man's story about how being faced with the hypocrisy, abuse of power, and systematic denial of accountability caused him to lose his faith. The religious leaders are supposed to be these great, moral people, so when they abuse their power, it's not just corruption, it's a let down of faith.

While religion and its people are two separate things, it's pretty understandable how incredibly immoral behavior from its leaders can reflect on the religion itself. When the corruption begins that high and is spread throughout the entire organization down to many of the pewsitters, yes, it can overshadow the good that is also done by the religion.

I'm not sure where you're coming from, but in the US, Christians tend to have the opposite problem of persecution. :D
