Here’s a great comment from one of my favorite bloggers. This guy is a very thoughtful Buddhist, and manages the “what is Buddhism” section of About.com. My paraphrased summary would be:
Every large organization contains people who do bad things, and sometimes truly awful things. Every. One. The measure of the organization is not how many of its members are perverts, but how they handle it. Do they close ranks and cover up, or do they act to stop it and prevent it in the future? For an institution devoted to advancing human morality to do this is really, really, bad.
