Would this not mean that there are atheists, and then there are atheist extremists, aka anti-theists?
As in many atheists’ blogs which I have seen (not all), there has been the use of terms such as moderate Christians and Christian extremists (labeled as fundamentalists). In following suit, there must also then be moderate Atheists and Atheist extremists. For there is the atheist which lives their life with a “lack of belief in any god”, then there is the atheist which appears to actively spend their life speaking, writing, blogging, and ranting against every religious thing that takes place.
The definition of moderates seems to be, they may concern themselves with belief or lack of, but do not interpose their beliefs onto others.
So we are left with the Christian extremists asking the Atheist to, “repent of your sin and believe in Christ for salvation”, and the Atheist extremists asking the Christian to, “turn away from Christianity and believe no longer in God.”
