You don't even know what an atheist is. An atheist does not believe in any god. He doesn't hate god any more than he hates unicorns. An atheist has no religion. Until you figure that out, you will never be able to engage in a reasonable discussion about the subject.
I know what an atheist is. I am married to one, and growing up, there were atheists in my family. None of these people visit an internet forum about religion any more than they visit internet forums about unicorns. I will not broad-brush all atheists who frequent religion forums as more bitter and resentful than atheistic, but frequently they are. True atheists do not ridicule God as a Magic Sky Fairy, nor are they resentful or bitter towards those who believe. True atheists know why they do not believe in God, and they understand why others do. Plus their understanding rises far above the atheist internet pablum of, "People believe in God because they are scared of death."
Again, there are a few Internet atheists here I greatly respect because they are much like the atheists in my life--and I am thankful for them. Mostly, "Internet Atheists on Religion Forums" give atheists a bad name and reinforce stereotypes of atheists, which is too bad and unfair to so many atheists.
