Atheism is less a conclusion naturally reached by evidence and more a symptom of a man's hatred of God. Atheists will often deny this, claiming it's impossible to hate that in which one does not believe. But Christian apologists are blessed in that we have a monotheistic worldview in a polytheistic world. We prove it is possible to hate gods one doesn't believe in every day. For example, as the meme above says, I hate Allah.
As a disclaimer, before the cries of "hate speech" fill the air, this does not, and I repeat, does not mean I hate Muslims. It does mean, however, that I am not especially thrilled with a god who claims to be the best of deceivers (Qur'an 3:54; 8:30), even to the point of tricking people into thinking Jesus was crucified (4:157), thus starting a religion whose followers Allah commands Muslims to fight against and violently subjugate (9:29). Nor am I ok with a god who calls Muhammad, a notorious paedophile (e.g. Bukhari vol. 7, #65) a "beautiful pattern of conduct" (33:21).
So, safe to say that I not only hate Allah, but I have some very good reasons to do so. Nevertheless, I would never extend my hatred of Allah to those who believe in him. If you are a Muslim, I do not hate you. In fact, in as much as your religion tells you not to take me as a friend (Qur'an 5:51), my religion commands me to love you even if you insist on being my enemy (Matthew 5:43-45).
But do atheists extend the same courtesy? This, really, is a hit and miss. Some atheists are lovely people. Others, not so much. Bill Nye is an excellent example here. Following the famous debate with Ken Ham, Ken extended the offer of friendship to Bill. Bill rejected the offer, saying he would prefer to be acquaintances. Since the debate, he has repeatedly slandered Ken.
Of course, this is just a prominent example, but a lot of atheists have little respect for Christians. One might even suggest that, if these people really don't believe in God, this is arguably even worse. It's easy to see how hatred of a God might cause one to hate His followers. But if that hatred is not for God, it is only for the people.
But as I say, not all atheists are hateful towards Christians. Some are so hateful towards Christians that it leads to violence, some are so loving towards Christians they may as well be considered honorary Christians (though unfortunately, God won't see it that way). Nevertheless the hatred of God is often shown from the effect His very name has on such atheists.
In fact, ironically, the very existence of atheism shows that God is seen as different from actual fictional characters. As Ricky Gervais pointed out, there is no word for people who deny the existence of Santa, or the Boogie Man. Gervais points this out in the hope of pushing the "lack of belief" redefinition of atheism that modern atheists use to avoid accountability, but what he's really highlighting is the fact that atheism is a serious intellectual position. That is, atheists don't treat God as being just a fictional character. They actively disbelieve in Him.
When you meet someone who still believes in Santa, the response is typically not one of disgust. More common are those who believe in ghosts. "Ok", you might think. "It's a bit weird, I'm not going to fight it too hard." If you tried to hold a convention to disprove the existence of the tooth fairy, no one would show up. Try selling a book purporting to prove there is no Easter Bunny, you'll probably go bankrupt. Yet, somehow, atheists actively seek to spread atheism, not just for their own peace of mind, but to seek to spread atheism as well. For example, Richard Dawkins prefaced The God Delusion with "If this book works as I intend, religious readers who open it will be atheists when they put it down."
Why such an effort? If you're an atheist reading this, ask yourself a question: Why are you even here? What caused you to see this article and actually decide to read this far? If you're a follower of the ministry, why?
I see two possibilities. The first is that you genuinely do hate God. Whether you admit it or not (I have had atheists admit it), you hate God, and will do everything in your power to keep Him out of your life (and ironically, in the process, are making Him a big part of it). Alternatively, perhaps you are willing to be convinced. There is a reason for this, and it has nothing to do with pond scum, lungfish or monkey men. Our brains are literally designed to seek God. The creation itself reveals Him to you, your conscience tells you He exists, you are here out of more than just a casual interest.
In both cases (though of course in the case of hatred, this isn't likely to hit home), I advise listening to that instinct and following God in faith. If you feel I have misjudged you, I ask a simple question: What motive do you have? If you believe this life is all you have, why waste it trying to convince other people that this is the only life they have? It's not like their fate will somehow be changed if you succeed in convincing them, after all. If there is no afterlife, both Christians and atheists share the same fate. Proselytising atheism makes no sense. Unless, of course, you hate the God you know exists.
