Nope, Project Hate is just as wrong as Chris.
The Theist-Atheist Scale discussed in The God Delusion is relevant to the real definition of "atheist." The rating system runs like this:
1.00: Strong theist. 100 percent possibility of God. In the words of C.G. Jung, 'I do not believe, I know.'
2.00: Very high probability but short of 100 per cent. De facto theist. 'I cannot know for certain, but I strongly believe in God and live my life on the assumption that he is there
3.00: Higher than 50 per cent but not very high. Technically agnostic but leaning towards theism. 'I am very uncertain, but I am inclined to believe in God.'
4.00: Exactly 50 per cent. Completely impartial agnostic. 'God's existence and non-existence are exactly equiprobable.'
5.00: Lower than 50 per cent but not very low. Technically agnostic but leaning towards atheism. 'I don't know whether God exists but I'm inclined to be sceptical.'
6.00: Very low probability, but short of zero. De facto atheist. 'I cannot know for certain but I think God is very improbable, and I live my life on the assumption that he is not there.'
7:00: Strong atheist. 'I know there is no God, with the same conviction as Jung 'knows' there is one.'
Dawkins says most atheists (himself included) (me, too!) rank 6 on this scale.
