I'm an academic and virtually all of my friends are atheists or agnostics. The agnostics tend not to make much of an issue of the debate, but virtually all the atheists I know go to great lengths to belittle believers, push their beliefs as scientifically proven, promote links to atheist rhetorical positions and propaganda, champion atheist intellectuals and their works like the Bible, and constantly blame religion for all the ills in society.  Compared to the atheists I know, the Mormons that knock on my door are puppy dogs when it comes to denunciations and propagation of belief.
