What is the difference between man's anger and God's anger?

I'm more interested in the similarity.  The idea that humans claiming to speak for a god are invariably angry at the same things they say their god is angry at.  

When God is angry he can destroy the whole world in a very short time..

A man's anger is small comparing to God's anger. God's anger may destroy the whole world. People must be very careful in God's matters.

God has all the facts; we rarely do.

Why would God have anger when he created everything and can make it anything he wants. The creation is created so perfect it wants what the creator has and thinks it has it but gets anger when it finds it not in total control and creating everything. 

Man's anger wants to punish whereas God's anger to put right.

The first one actually exists, the second one doesn't. Why would I assume that "god is real" when I don't believe any god exists?

God's anger is more like the grief a father feels when he sees his daughter getting off the back of her new boyfriend's Harley sporting a new tattoo of wings spanning her back.

His love never fails, but He shakes his head at the absurd folly of His creatures.

We can really get pissed off like a cop, but God has the ability to sent one to hell, 

Man's anger is real.  We know it is real because we can measure brain activity, facial expressions, body positions and other physiological reactions when we experience the emotion called "anger".

God's anger is mythological.  We know it is mythological because it cannot be detected at all.  God's anger is no different than God's joy, sadness, love, jealousy, etc. etc. and results in no influence on the natural world.

If God's anger does not influence the natural world then it is the same as not existing at all.
