Because according to Islam, unveiled, unaccompanied women in public are asking for it therefore rape is ok with them.
Heck, rape - including gang rape - including village wide gang rape - is an punishment that can be administered to women in accordance to Sharia Law.
Does that mean no one else commits rape?
Of course not.
Does that mean no other religion condones rape under certain circumstances?
You let me know when you find out.
