Amish and Mennonite women in the U.S. continue to wear scarves to this date. If Muslim women opt to wear scarves in public it is their right which should be honored and respected without prejudice. Islam is criticized for harsh punishments for criminals, such as amputation of hands of convicted thieves, death for convicted adulterers and so on. Yes, Islam prescribes such punishments provided harsh conditions are met for the conviction. There must be two or more eye witnesses of credible character for conviction and for ultimate punishments to be applied.
Circumstantial evidence deserves only lighter punishments.
However, Muslims have abusive rulers, and for the sake of popularity, apply ultimate harsh punishment without meeting the requirements of evidence or conditions. In America, there is a lot of corruption in the legal system. In the U.S. simple divorces take years to settle. It is also known that over forty percent of convictions are false, which means that over forty percent of criminals go scot-free and in their place innocent people are being jailed. Besides, convicted criminals, who have lost their credibility, become witnesses against their own former friends for seeking leniency in their own prison terms.
