Atheists won't win.
Win what?
You are fighting a war that you will lose.
A war? Are you talking about Iraq, or Afghanistan, 'cause that wouldn't make sense. Those wars were started by a fundy president with a lust for oil.
Bus adverts,
Oh that! Those are tame. If you feel threatened by those, it says something about you and your faith.
atheist bibles,
LOLWHUT? Atheists don't have bibles. We have no god, no doctrine, and we hold no book or philosophy as sacred.
lying about Christianity,
We don't need to. It's ugly enough as it is.
taking God out of public life,
If by "taking out of public life" you mean "taking out of the law and legislation", than yes. Otherwise, no.
We do not believe as you do, and we do no appreciate you making us act as though we do.
promoting just about everything the Bible forbids,
Like eating shrimp, being gay, and wearing cotton and wool at the same time? Not really. We just happen to think it's completely retarded to forbid those things.
taking sides with Islam when it suits you to attack Christianity,
No. We think islam is as bad as (or worse than) christianity, and we want that to go the way of Zeus along with your beliefs.
invoking Zeus Father Christmas fairies etc.
Only to show you how we view your god, and your belief in that god. We think it's retarded to believe in a god.
none of it is going to work.
Evidently. Must be because your skull is so thick and dense.
You will not win. You will lose. Big time. The reason is simple- you are fighting against God. So, you will lose. Even a simpleton understands that.
Your imaginary friend can not stop us. The only opposition we have is your idiocy, and I must admit, that is something of a problem. As long as you want to stay stupid we can't really win, but maybe we can educate some of you out of idiocy and ignorance.
If God didn't exist it wouldn't be such a struggle for you, would it. Everyone would be atheists. We're not.
If a good god exists there would be only one religion, and it would be a unifying one. Any holy scriptures such a religion would have, would reveal profound mysteries of the universe and truly great morality, and guide all mankind in peace and teach us how to live in harmony with the rest of the universe. Christianity and all other religions fail on all accounts.
