[I often use the term ‘New Atheist’ b]ecause it’s shorter and simpler than “anti-theistic atheist activist” or some other similarly cumbersome but more exact phrase. Not all atheists are anti-theistic (on the whole, I’m not) and not all are activists. I tend to find that it is the anti-theistic activists who are most likely to accept anti-religious pseudo history uncritically, to use it in their arguments and to reject any correction of it as “apologism” or “revisionism”. They are who I’m referring to by the shorthand term “New Atheists”.
