If someone told you that they were chosen by God, and they were above all other people, because God chose them, and different laws applied to them because they were chosen by God, would you think that person was crazy?

...

What if I told you there is an entire people who think they were chosen by God? A religion that believes that they are better than any other people because they are all descendants of the same person? People who are not descended from this single person have not been "chosen" by God... This must surely be an awful, depraved religion if it were to exist.

If people were to follow this religion, they would surely do devious, dastardly things. They would attempt to have one set of laws for dealing with themselves, and another set of laws for dealing with people who were not "chosen". They would never truly make themselves citizen of any nation they go to, for they would be only ever truly be citizens of the nation "God" granted them. They would do anything for this nation.

They might even enter other nations, and attempt to become citizens. They might mimic the character of the people. They might try to take advantage of other races, and sew division in order to entice the people quarrel with each other, only in order to distract them from their own crimes...

Surely, if such a religion actually did exist, it would be considered evil, right?

Briefly: They are not Christian. Stop expecting them to act like Christians.
