For too long, atheists, agnostics and all other manner of non-believers have been told by society, in essence, there's something wrong with not believing in God. This comes in the form of open hostility and concern for the atheist "soul" with comments such as "we're praying for you that you find God." Personally, I feel quite content with my atheism and with living a life guided by the principles of humanism and ethics not based on the existence of a supernatural overseer. When religious family and friends tell me they are praying for me, I try to focus on the good intention behind their doing so while also communicating to them that I feel no lack in my spiritual life that needs to be filled by faith. While there have been great people of all manner of belief systems throughout time, below I have posted a great youtube clip which does a little boasting for us non-believers.
Some organizations that provide a community for non-believers:
American Humanist Association
Freedom From Religion Foundation
Richard Dawkins Foundation for Reason and Science
American Atheists
