The woman in the headscarf is posing a threat to safety and security of a nation, and the woman in the bikini does not pose a threat to the safety and security of any nation. Bible says go to the places that people welcome you. Also, when people asked Jesus who should, we pay our taxes? He said to the Caesar. He taught people to integrate into the society. Since the woman in the headscarf loves Islam, she can live in Saudi Arabia where Islamic laws are observed.
