The men of her city must stone her to death because she has committed such a godless act in Israel.

This quote is not from the Qu'ran. This atrocity is the word of god according to the Christian bible (as if a god was real and it was a thug).

What's the difference between Muslim terrorists and Christian assholes?

There's no difference at all. They both believe in a disgusting ancient book full of violence and stupidity.

From Deuteronomy 22:

But if the charge is true, and no evidence that the girl was a virgin can be found, they must take the girl to the entrance of her father's house. The men of her city must stone her to death because she has committed such a godless act in Israel: She had sex before marriage, while she was still living in her father's house. You must get rid of this evil.
