Perhaps there are only agnostics, as we have all questions we do not know how to answer and we all throw our best guess at it, based on the information (we think) we have.
Why is a believer called just that, because he beliefs in god, he does not know god, at the very least not in his entirity.
And the notion that an agnostic would have to go to church half the time is really ridiculous. What church? If I have not enough knowledge to vote for one of the 30 political parties in my country, should I vote for a different one in the 30 next upcoming elections?
Agnostics cannot be consistent with their belief, because they have no belief, because they don't think they have enough knowledge to belief. The only consistent thing for an agnostic to do is gather more knowledge, perhaps even in a church or a mosque.
Once again, you're welcome
