I don't hate "atheists," but I do hate "atheism." In my opinion, it is the most irrational, dangerous, diabolical, contradictory, and foolish theories that mankind has ever formulated as a philosophy and view of the world. Therefore, I, as a Christian theist, will continue to seek its destruction until it is eradicated from the world as a system of thought and lifestyle.
In passing, I would say that "atheists" hate theists more than theists hate them because "atheists" love sin and hate God, by nature. One can only think of the Christian hate speeches of Christopher Hitchens, Richard Dawkins, and Sam Harris, as international spokesman of "atheism." If you want to witness hatred and aggression as you've never seen in a human being, just read any of their works or listen to their speeches. It will definitely send chills up your spine and make your blood boil. It's just too bad these guys will have to face an angry and righteous God on Judgment Day to give an account of their perpetual hate, aggression, and ridicule towards God's people (unless they turn from their wicked ways and believe in the truth of God's revelation).
Anyway, for me, "atheists" aren't the problem because they are made in the image and likeness of their Creator, though they daily refuse to acknowledge Him as such. It's "atheism" that's the problem, and as I've said before, I will work diligently to bring its demise to the human race as long as the living God blesses me with breath in my body and His Spirit in my soul. Having said that, I try hard to love "atheists" as my neighbors on God's earth, though I fail to do that at times, I admit.
So much for "atheists" trying to attain peace in the world. As long as theists exist, you will never have peace because your "atheism" will be a threat to us. Oh, what will you do?
