It's a common christian trope to claim that atheists are just 'mad at god' or 'hate god'.

It doesn't help that many famous 'ex-atheists' like Lee Strobel (of 'The Case for Christ' fame) and others who found that they could get attention by sharing their 'conversion stories' (christians love a good conversion story) describe their time as 'atheists' by claiming that they were 'just so angry with god' or 'hated god' for one reason or another.

It's standard issue b.s.

Prove that God does not exist and your assertion might even become intelligent.  Try not to beg the question. 

The answer is that they want to believe it.

But tell the truth for once.  If you loved the idea of God, you would move mountains to experience him for yourself.

Because it is the truth.

God does exist the self claimed Atheists actually know God exists they just hate Him and reject Him.

It's a way to demonize atheists. Some Christians say atheists are satanic. It makes it easier to dismiss atheists' arguments.

They are not known for rational thinking.

Logically it's impossible. But we know logic is not the strong point of atheists. Claiming to be logical is one of them, but actually applying it...............

Maybe if fewer atheists ranted and raved about how God doesn't exist and Noah's ark never existed, and in the same paragraph expressing how evil God is for killing everyone in a big flood.
