Joel Grus recently published a book titled "Ten Stupid Things Smart Christians Believe" which is basically a blatant attack on Christianity. He listed his ten points that are "explained" in the book, on his website.
His second point:
2. There’s an invisible man in the sky who likes to watch you while you’re showering.
First of all, God is not an invisible man. He makes himself known very clearly through miraculous works and through a certain extremely popular book called "The Bible." Secondly, He doesn't "like to watch you" like some spectral pervert, he watches you so he can take care of you and because he does care about you. The other nine points are just as poorly thought out and insulting. Joel is obviously having some problems with his conscious and takes his frustration out on those who's thoughts are more put together than his.
