When people say that they are agnostic, that they don't believe humans can ever really know anything about God, are they just being apathetic?

When people say that they are atheistic, are they zealously making a stand when they should be tempering their beliefs with some humble agnosticism?

And what of the believers, the faithful? If they're being apathetic about their religion, are they committing a greater offense than if they took a spirited, principled stand as atheists, or possibly even agnostics?

As a resident Jewcy Catholic, I think about these things.
