Nice offering on the Atheist Meme front from Greta Christina today.
Very few claims can be proven or disproven with 100% certainty. But we can still assess whether those claims are more or less likely to be true. And that includes religion. Atheism doesn't mean 100% certainty that there is no God: it's the conclusion that the God hypothesis is not plausible. Pass it on: if we say it enough times to enough people, it may get across.
We can only hope.
