No, an atheist is one who is convinced that there is no god. He is not someone who simply lacks a belief in some sort of deity.
That is one possible definition and is generally termed "strong atheism." There is a difference, though, between atheists who are decidedly against the possibility of there being a god and atheists who do not believe in a god because they see no evidence, but would if they found evidence.

[A] person who denies or disbelieves the existence of a supreme being or beings.
Both acknowledge the affirmative (strong) and agnostic (weak) versions of atheism. The strong atheist outright denies the possibility of there being deities (and generally anything supernatural), while the weak atheist lacks belief at the current moment because they see no evidence for it. A weak atheist is closer to agnosticism, but is separate from it. The agnostic has the decided position of "I don't know," whereas the weak atheist has the decided position of "I don't believe in gods because there's no evidence for any." It's a small distinction (agnosticism vs weak atheism, that is), but it is a distinction.
But that aside, I don't mind atheists. They are often kind and thoughtful people who just don't believe in a supreme being. As for what to do about it, we do best to let our own lifestyles speak for our faith.
This is true. There are some people who say that anyone who is not religious, or indeed not Christian, are incapable of having morals or are always moral relativists. Such a thing is not true.
I do find it interesting, though, to read people here saying that they were non-believers at one time and then chose what is arguably the most ceremonial, self-satisfied, and mysterious variety of Christianity that there is--Eastern Orthodoxy. Does this movement all the way from the far end of the religious spectrum to the other end, a 180 degree turnabout, have less to do with theology than with the emotional needs of the convert?
So would a conversion to something like a Protestant denomination be less "emotional?" From my own personal experience, I would have to disagree with this statement. Besides there being plenty of areligious people who have converted to things other than Orthdoxy, it was my personal experience that my conversion to a variety of Christianity with apostolic succession had more answers and deeper theology than most Protestant denominations. I cannot say, then, that my conversion (though it wasn't to Orthodoxy) is due to emotionalism. It was due to my perception of Catholicism being the best expression of Christian theology and doctrine.
