I don't have a problem with people who are atheist or theist or
  any ol' ist or any ism they wanna be. Agnostic for me is just: I
  don't know. Maybe somebody else does and I say, "Good for them!"
  Just as long as they don't bug me *too* much about converting to
  their way, even if it's the middle way == Individuals matter to
  me. Affiliating with something doesn't matter quite as much to
  me. But if rallying for a cause means something to you, go for
  it. ==
