On the contrary, he was an enabler and covered up for abusers except when it was politically useful to take action against them.
As more and more evidence comes out, it's abundantly clear that Wuerl is a liar. He's also a promoter of dissenting gay propagandist Fr. James Martin, S.J. which says a lot about his seriousness to address the horrors of homosexual sex abuse. Martin supports gay unions, the right to sodomy, and other mortally sinful behavior. Wuerl's support for him says a lot about where he stands on the sexual moral issues. As my mom always said, "Birds of a feather flock together" and "Show me your friends and I'll tell you who you are."
