But they won’t win in America. Technically America doesn’t have to ban Muslims to keep additional Muslims from immigrating. No country has 100% Muslims so America can ban, for example people from the 20 or so countries that are ruled by Muslims.
If there were no Terrorists in America there wouldn’t be a problem with terrorists but about 1% of Americans are Muslims. That’s about 3 million who believe that shariah is “The Muslim God Allah’s law that Muslims must follow and impose worldwide by Jihad” according to the Center for Security Policy’s survey of Muslims in America Poll.
