To whom did God give the Ten Commandments? Not to us. To the people of Ancient Israel. Ancient Israel no longer exists. They were destroyed 70 AD by the Romans.
So, the people of God are only the Ancient Israel people, if I remember right even in the new testament says that only the people of the 12 tribes of Israel are going to heaven and why are people who aren't from Israel fallowing a religion that doesn't mention people from other places? And how do you know that is only for them? Do he, she or it put a topic to the letter, e-mail, telegram or whatever like: "Only to people of Israel" or a PD like: "Until X of month Y and year Z". How do you know that "Love God above all things, and your neighbor as yourself." is for us and not only to Ancient Israel people? Did he, she or it specify it?
And Romans destroyed the Ancient Israel? It seems like Yawe or whatever the name is, is not so powerful if he, she or it let them die.
Didn't you say that you read most of the Bible through? Did you forget most of what you read?
It's an extremely good thing that you are asking questions. But ask them from a standpoint of believing what God says, not trying to pick on Him because you think He is unfair.
Remember that I was picking on you for picking on CoinCube in the wrong way... without knowing what the Bible says... or do you know?
Just because the Word of God was given to the Jews or Hebrew people, doesn't necessarily mean that it doesn't apply to other people, as well. But if you don't know where the Bible talks about such application, or if it does, why aren't you into it to find out what it says? Because it tells you when the commandments are for you, and when they are not. You are alive, so find your position in life as it is written in the Bible.
Visit with a local Pastor of a local Bible church, and he will show you the parts of the Bible that apply to you and why.
