  • Love it.

    I first started listening to Paper Ghosts and then came over to Crossing the Line. And I absolutely love it and I love M William Phelps. It is quite apparent that victim advocacy is a strong passion of his, and he does it well, regardless of the media or opinions. And facts don’t care about your feelings.

    Love this show!

    Mr. Phelps has this amazing ability to help you visualize everyone he’s having a discussion with. He is the perfect balance in his interview interviews of empathy and darkness. You can’t help it be caught up between the drama and the sadness he’s trying to project. His sense of righteousness is not overbearing. It’s actually extremely comforting. His podcast by far is my favorite.
