Most of the people I know have higher standards than this god. Honorable people don't lie just because their truths are rejected.
Look at the quote above. You called your god a liar in the second sentence. You know what a liar is, don't you? It's anybody who knowingly deceives. If I send you a lie, you can call me a liar, and I reserve that right even when considering alleged gods.
You have no truth. You're a faith-based thinker, and faith is not a path to truth. Do you consider your god actual? Then you do so by faith, since you not only have no evidence that the Christian god exists, but must ignore compelling evidence to the contrary that it cannot exist given that is said to have mutually exclusive properties at the same time - a logical impossibility. You have been lied to by the Bible's writers. Atheists see through the lies.
Even without this compelling evidence against the Christian god's existence, if faith is a path to truth, one can simply reject the claim by faith and have as good an argument and as much truth as you have.
Just so you know, when you make blanket, bigoted statements demeaning the intelligence and integrity of all atheists - a class of mostly law-abiding, hard-working people trying to raise their families and make their communities better - you earn the contempt of those people, and invite a similar review of your religion and the effect it would have on anybody that would listen to and assimilate its hatreds. Christianity brings me nothing of value to me, but it does generate millions of bigots and poor thinkers demeaning people like me for having the sense and strength to avoid the pitfall of hating by faith.
