Omniscience-Human Experience Incompatibility Argument

There seems to be a lot of these recycled arguments that claim that God cannot be omniscient because His divine nature precludes him from certain types of knowledge, such as knowledge of sin, or knowledge of what it is like to learn. Here is yet another of these arguments.

1. Fear is a feeling of agitation and anxiety caused by the presence or imminence of danger. (The American Heritage® Dictionary: 2000) 
2. If God exists, God cannot feel agitated, anxious or feel endangered. 
3. If God cannot know fear, he is not all-knowing. (Some would claim that it is against God's nature to be afraid. Exactly, then he cannot be omniscient. There are at least some things for which he is completely ignorant of. Stating that it's against his nature is a cop-out and a concession simultaneously.) 

It's basically the same argument those linked above, so it gets the same response.
