Axioms and math.

Militant atheist: "2 + 2 = 4" is not "absolute," but contingent on a set of axioms like ZFC. It's validity within such frameworks is absolute, though.

Militant's atheist political views are "very liberal" as he noted on his facebook page with this quote:

"I would describe myself as a communist, and I think most people I know would too. I am commonly asked why I behave as if the world around me were already (or were at least on its way to becoming) the world I wish it to be; to that I can only reply by pointing to this: "We need to be the change we wish to see in the world." -Mahatma Gandhi
