While Yeng is right about some of them overlapping, not all atheists are skeptics.

And I question whether you're a Christian or not. As you have an evil character from the Smurfs in your picture. And Christians say that the Smurfs are Satanic.

At least they did when I was kid, I wasn't able to watch the Smurfs.

Some of them overlap. If you are an atheist, you also are a skeptic.
