Ah, the No True Scotsman Fallacy. You're really big on logical fallacies, aren't you?
Christian's don't exercise morality. They just do what they're told by some "absolute" authority. Just obeying orders.
No, I don't think thought crimes are immoral. We've all thought of things we'd never actually do in real life, I'm sure. And thoughts aren't really something that can't be controlled in such a manner.
Who says turning the other cheek rather than retaliating is always the most moral choice? Should we have turned the other cheek to Hitler and the Nazis?
"Sex is only for marriage" is a religious precept, based on the writings of ancient peoples whom are claimed to speak for god(s), with no evidence of such whatsoever. And no demonstration that it's actually immoral.
"Drugs and intoxication" isn't immoral on its own, unless someone is being harmed.
The system of morality I follow is based on humanism. The goal of morality, in my opinion, is to maximize the well-being of sentient creatures. Actions that result in that, are moral actions and actions that result in the harm of sentient creatures, are immoral actions. These will be dependent upon the situation. For instance, lying can be moral in one situation, like say, if you're hiding Anne Frank in your attic and the Nazis coming looking for her, the most moral action in that situation would be to lie to the Nazis. In other situations, lying can be immoral, like if you told your spouse you loved them and are faithful to them, while simultaneously having a love affair with another person.
Your code is subjective - it's literally based on the whims of a god. Whatever that god says is good is good, and whatever that god says is bad, is bad. There is no weighing out of moral decisions as to the consequences of their actions on ourselves and those around us. Nope, just do what the god says!
