There is a surprisingly large number of Christian's that hate God so much that they create their own god.
Well, how do you personally feel about him?
Do you hate him?
Do you love him?
Do you pretend to love God but made up your own god that is better than the one in the Bible?
Are you apathetic toward God?
There is so much wrong with what you wrote. First of all, a Christian doesn't hate God so much that they create their own god. They believe there is and always will be only one god just like you. What you are describing is a former Christian who realizes that Christianity is just another religion just like all the other religions. So they leave the church and start their own personal relationship to the one and only god. They, like Christians, believe there is one and only one god. So they start their own little personal relationship with god. If they hate anything it's Christianity and Christians. See the difference? They don't hate god.
But if they do, then they are theists not atheists. Because they still believe in God. I know about this because I used to be one of these people. This is the first step towards waking up and realizing there is no god.
