Weak atheism..
The weak atheism conclusion is that there is no reason to believe in God or gods, for reasons other than evidence of their nonexistence.
Weak atheists argue that merely pointing out the flaws or lack of soundness in all arguments for the existence of God is sufficient to show that God's existence is less probable than his nonexistence; by Occam's Razor (the principle of parsimony), the burden of proof lies on the advocate of that alternative which is less probable. By this reasoning, an atheist who is able to refute any argument for the existence of God encountered is justified in taking an atheist view; atheism is thus the "default" position. This objection is often stated in terms that relate it to the burden of proof: It is incumbent upon advocates of a God's existence to establish that fact, and they have not done so.
Just wanted to point out, without naming any names, that there're alot of weak atheists here at KMC so far from what I've been reading, again without saying any names.
I'd say the majority. You know who you are.
