I don't know his point in debating Catholics, unless he assumes he's gonna wake up a few members and they'll start worshiping him for his wisdom and saving them from the horrors of church.
What of his followers that never were JWs and are Catholics or left Watchtower to become Catholics? Did he even think this plan through? Is Lloyd's plan to alienate the remainder of his ever decreasing audience? It amuses me that he is so militant atheist and so determined to be right about everything that he will risk ruining the remainder of his following. Yes there is a growing segment that doesn't believe in god. There is a larger percentage that doesn't care if there is a god, doesn't have an opinion, or believes it is a personal decision where a organized religion is unnecessary. The ones like that aren't looking for his channel. They are watching other videos on YouTube far more interesting.
