"Which of you, if his son asks for bread, will give him a stone? Or if he asks for a fish, will give him a snake? If you, then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask him! So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets."

You've asked a question, but you've expressed you disappointment and disgust with some of the opinions/answers you've received.
How are you deciding which answers are right, and which are wrong? What rule, what guide, what plumb-line are you using? In short, how do you know whether you are right about the nature and behavior of God?
You see, the difficult question you need to answer is "By what standards do we judge God's behavior?" What moral code can we call upon, that exists independent of Him and His creation? What judge do you appeal to, that you can sue God in front of to accuse Him of unfair behavior?
Some of us believe that God is capable of not been silent in history, and we believe His words and actions have been documented for us to understand Him by (and, to answer another charge, we believe He is fully capable of maintaining the accuracy of this documentation). Rather than insist He modify his behavior to fit our opinions, we allow him to correct our misunderstandings about Him.
All I'm saying is that you may not like the answers you hear, but that doesn't automatically mean they're not right.
