Justin Brierley said that rape was absolutely morally wrong, and would be , even if he belonged to a specied that had evolved to believe that rape was right.

The Bible agrees, and says rape is wrong. At least, the rape of a virgin is wrong.

Deuteronomy 22
If a man happens to meet a virgin who is not pledged to be married and rapes her and they are discovered, he shall pay the girl's father fifty shekels of silver. He must marry the girl, for he has violated her. He can never divorce her as long as he lives.

Absolute morality or Biblical morality? The choice is clear.
