Within both atheist and Christian dialogues, it often seems that agnostics are dismissed as "fence-sitters" - people who simply can't decide what to believe. The weird underlying assumption always seems to be that the "fence" is between Christianity and Atheism. As if I think to myself, "Maybe the Bible is true. Or maybe not. I just can't decide."
That is silly, and that has nothing to do with agnosticism. Contrary to popular understanding, 'atheist' and 'agnostic' are not mutually exclusive terms. (A)theism is about belief, while (a)gnostism is about knowledge. If you do not personally believe in a god but you do not claim to know the truth, you are an agnostic atheist.
There are other ways of thinking about the world beyond the framework of accepting or rejecting Western religion. There is an infinite number of ways you could carve out your own personal understanding of the world, and yet there is no way to ever be certain that you are right.
I am an agnostic. To me, that is simply a matter of accepting the unknowable with a sense of humility. I'm not having a hard time making up my mind. I've decided not to claim knowledge of something that I cannot possibly have evidence for. That is all.
