There doesn't have to be a point. People believe what they think is true. If they think that organized religion is problematic, but that some sort of God exists, that's what they believe. They don't need an agenda. For some, it's part of the process of becoming an atheist: lose faith in organized religion first, lose faith in the existence of God next. Or they might stick with deism or 'mere theism' for the rest of their lives.
I'm not anti-Christian. I'm anti-stupid.
