I admire Dawkins' style and clarity of writing, and I have read a few of his books on evolution and found them lucid and fascinating - rare for a science text. However, I find his views on atheism every bit as arrogant and annoying as people who preach their religion at people who don't care.

Stridently yelling that there is/isn't a God is the least successful way to convert someone's view on the matter.
