"Some people assert that atheism means nothing more than "lacking belief in gods", and that we shouldn't try to make it anything more than that. And on a purely lexicographic level, I agree. Anyone who lacks belief in gods is an atheist, no matter what I may think of their personal or political views on other subjects. But if we're going to build an atheist community - that is to say, an organized movement whose members can support each other, motivate each other, work together to lobby politicians, and cooperate to improve atheism's public reputation - then we have to have a little more in common than just that bare foundation of godlessness.
...the success of atheism is inextricably tied with the success of progressivism and social justice. The most effective way yet discovered to weaken the influence of anti-intellectual fundamentalism is to create a more prosperous, more egalitarian society where the illusory comforts of religion have less appeal. The conservative-libertarian worldview, which treats high levels of inequality and economic instability as a feature and not a bug, will thus never be able to banish the specter of superstition. This is a self-contradiction that I believe atheists who hold to this worldview have never fully faced up to."
