Atheists turning to cult behaviour?

[Silver]

Secondly, you seem to argue its more important to make sure Atheism is not defined as a religion, than making sure that Atheists dont behave exactly the way religious people do.

When an atheist behaves inhumanely, there is no religious connotation behind the behavior. The misnomer is in the clear and unnecessary comparison you may be, or may not be, inadvertently making between relative inhumane behavior and theism.
