Simple answer to a difficult problem.
If you take the responsability of what you just said that is fine with me.
An Atheist has probably the most difficult task: Assume responsibility.
Unlike theists we lack a deity to blame.
So yes, I take such responsibility on my daily actions.
Blaming someone else for something that we do is mostly an atheist thing. Most theist religions show the blame to be our own. Atheism often wants to blame theists for problems in the world. Look at all the wars that are attributed to religion right in this thread.
