Youve heard about atheism, a state of being where an individual has concluded that there is no God, or gods for that matter.
Then came Atheism (with a capital A, in case you missed it) which is essentially what I practice here. You can call this one militant atheism or anti-theism. This is the second wave of theism, made famous by some brilliant, eloquent, and lucid critical thinkers like the four horsemen, Richard Dawkins, Christopher Hitchens, Sam Harris, and Daniel Dennett. Brandishing bestsellers and taking the stage on radio, television, and other venues, they brought Atheism into the spotlight.
What makes the second wave of Atheism different from atheism (with a lower case a) is that people like myself tend to get vocal about not believing in God or gods or any kind. We get vocal because we are convinced, by the sheer weight of historical evidence, that religion and the belief in gods is dangerous. We might go so far as to suggest that religion is the enemy of civilization and anathema to our very survival as a species. The Atheist (or anti-theist) spends time and energy trying to convince his or her fellow human beings that we would all be much better off if religion wasn't part of the discussion. To support that argument, Atheists will directly confront religious belief and try to create an argument whereby the believer might be convinced to, at the very least, question their belief. With luck, that person will develop critical thinking skills and a healthy talent for skepticism resulting in a love of reason.
Plain old lower case atheists just plain don't believe in god and they may or may not see any reason to chat about it with any one. They're atheists and that's pretty much that.
Then we have Atheism+ which is Atheism with a little something extra. It's a community of Atheists that believe atheists (both with a lowercase and uppercase a) should concern themselves with other issues, such as women's rights, LGBT rights, social activism, poverty, racism, homophobia, and, oh yeah, atheism. It kind of like Atheism PLUS. You see? It has been described as a third wave of atheism, partly rejecting the second wave of old guys pushing bestsellers, the aforementioned New Atheism.
If you're looking at atheism and Atheism isn't enough and Atheism+ hasn't quite got the issues covered for you, you are in luck.
