I suppose they are better than Muslims in that they won't kill you for not believing as they do... but hearing their crap over and over does get irritating after continually telling them to quit it.
I have an atheist friend (not the one who said the ridiculous statement on evolution. I happen to meet more than my share of atheists, including Hitchins because of my journalist/professor friend that I am talking about now) who wrote an excellent article warning atheist of falling into a dogma of their own.
It was a good article. It is not their job to preach to others. She dislikes Dawkins for this reason.
