Yeah, they definitely come across as the more militant atheist type to me. Not so much the "I don't believe in a deity, please respect that and stop trying to convert me" type as the "there is no deity, you are stupid for believing so, I am suing you because you decorated your office in accordance with your faith" type. Ironically, atheists who embody many of the traits that turn people off to blowhard theists. Which is too bad, because there are definitely important issues that they try to address, but their heavy-handed approach makes it easier to dismiss them as irrational and intolerant.
