If atheists treated Christians like many Christians treat atheists...

If we could simply ask him, the religious wouldn't be so divided.

How do you know that? You've presumed that if God were to answer the question of 'why such division's exist' that would necessitate there would be no divisions.

That's what Darkmatter is getting at. Jews, christians, and muslims all worship the same god, yet they can't come to a consensus on who is on the correct path.

Does it follow then that they worship the same God? Maybe the problem is that they aren't worshiping the same God and these divisions exist to clarify truth from falsity.

If my dad says something individually to my mother, my sister, and I, we might disagree with exactly what he said, but we can simply go back to him and straighten it out. We don't have to start beating each other up over what he said.

I agree.

We can't simply ask god for answers, otherwise we would have already gotten it. If he hasn't straightened things out by now he either doesn't exist, doesn't care, or is unable to do anything about it.

Seems like a false trichotomy there. This line of reasoning is akin to the argument against God because of the existence of evil. Most philosopher's have abandoned this line of reasoning because of the hidden premise in the argument: that the evil (or in our case divisions) is meaningless. You've assumed that there aren't any good reasons for these divisions.

I still maintain the original argument is fallacious. Divisions do not necessitate non-existence. There is the A-series and the B-series theories of time. Certainly, because there is division over the interpretation of time, you wouldn't conclude that time does not exist. Or science does not exist. Or scientists do not exist. You would most likely conclude 'we don't have all the answers yet,' and be satisfied.
