Too many to name. In fact, if you reckon all the logically possible atheistic worldviews, the number will be infinite. But even if you only count worldviews actually embraced, there are too many to survey. They range from Marxism (radical socialism) to Objectivism (radical capitalism) and everything in between. Even some supernatural worldviews, like forms of Taoism and Buddhism, are atheistic. I advocate a politically moderate Naturalism and Secular Humanism, but even those have diverse possibilities within them that are still healthily debated. As we are not dogmatists, we do not consider the truth to be settled, but accept and encourage constant inquiry and debate over the correct beliefs to hold.

What's an easy way to demonstrate that unitarianism is false?
By what means or method do you check that what you believe is true, is true?
