Yes 'agnostic' is less confrontational than 'atheist'. Atheists eat babies while agnostics are just indecisive weasels
There is a range of skeptical positions that come under the umbrella of atheism and agnosticism. It's more important to understand a person's actual position than it is to be able to label him as atheist agnostic etc.
In very broad terms, the most common flavors of skeptical positions on the matter of the existence of God are:
Strong Atheism: Asserts that God does not exist.
Atheism: Does not believe that God exists.
Agnosticism 1 Unsure of the existence of God.
Agnosticism 2 Believes God is unknowable.
The Athiest position is that he sees no reason to believe in God any more than he does in unicorns but if confronted with a live unicorn or compelling evidence for God (what could this be?), he would reconsider. So yes, he doesn't claim absolute certainty and there is an element of doubt. Nevertheless this is a strong position. When we make plans we completely discount the possibility of unicorns showing up. The Atheist feels the same way about God.
Agnostic 1 is unconvinced but he considers the existence of God a serious possibility, something that needs to be taken into account.
None of these statements make a lot of sense until we define what we mean by 'God'. One can be an atheist about one kind of God and an agnostic or even a believer about another.
