You're anti-theist, not an atheist. Get your bearings right for a start.
I'm an atheist and I don't care what others believe, as long as their personal belief does not intrude on my life, which is safeguarded on most modern countries.
Try to get away from fundamentalists and get to know people that keep some sort of creed for personal comfort or some other aspiration unatainable by the unpassioned scientic analysis.
What we all should be aware of is that science constantly reminds us there is more to what we don't know than what we effectively know and the tools we have available to push back our ignorance are few and limited by our own nature.
Your disgruntle and discontent with belief is not a new subject. You are not alone and what you perceive as a low in our colective history is just a very slight down turn on a very long climb towards moving away from the darkness that hides in our minds.
