I think Perry actually just admitted a very important thing: that he couldn't manage to live a successful life on his own.
Doesn't this sound like AA when alcoholics admit that their lives have become unmanageable? Then AA provides the structure to get their lives back on track? Fundamentalist Christianity serves the same role as AA. It provides structure for people who are having life difficulties.
And when they preach, it's like they assume that everyone else is having difficulties, too. It's like it is relieving to believe and tell others that everyone is a sinner. I think that's ultimately what is so offensive to others. It sounds like an assumption that everyone's life is as messed up as yours.
Many of us have happy marriages, children and careers. We haven't ever needed the structure of religion to keep us on the straight and narrow, in fact that life sounds suffocating and detrimental to healthy living and happiness. We neither want nor need to blame the bad things in our life on Satan and we don't need a god to help us to handle life.
I can't imagine anything more miserable than being involved in the strictures of religion again. Why can't fundamentalists realize that their heaven feels like hell to us?
