Sharia requires 4 male witnesses to the act of adultery to convict a woman....Sounds like the barbarians only want a gang bang.
Right. But under Sharia the male adulterer is also executed. Or is supposed to be.
Of course, for a male adultery is defined only as sex with a married women, as it was under the Law of Moses. A married man having sex with an unmarried woman is not committing adultery.
