Yet many people when asked if they were atheist would say, "actually I'm agnostic," to distance themselves from the anti-religious. In my experiences, there's been a clear accepted difference between atheism and agnosticism in our language.
While atheists on both ends of the spectrum may be cowed into the "weaker" position philosophically, behavior tells the whole story. When Richard Dawkins, Sam Harris, or any other atheists openly mock religions and their followers, their behavior betrays a position much "stronger" than simple ignorance of god(s).
(NOTE: I use "weak" and "strong" with quotes in the context of atheism to express my belief that the "weak" atheist position is the much stronger one to hold. I have no problem with agnostics calling themselves atheists, yet I still believe the difference between the two positions is significant.)
