Strong and weak atheism

Atheism is a matter of belief, or more accurately, a matter of non-belief.  An atheist does not believe in god or gods.  But there are some atheists, myself included, that take things at step further.  I believe gods do not exist. Some people call this positive statement "strong atheism."  Some say it is unnecessary, and places a burden of proof on the atheist that should not be there. I'll give my perspective on this, and how it has changed.  I'l talk about what exactly I believe and why. Plus your calls.  I believe the awesome sause will flow.  Prove me right!
