Either we deal with Islam now through policies and laws, or we do it in the future with violence and bullets. Islam is a spiritual plague that should be isolated and controlled, not allowed, even encouraged, to infect everyone.
Oklahoma tried to pass a law pre-empting sharia from ever being implemented, a judge struck it down after CAIR took it to court. Why would the US need to have an opening for sharia law to ever be implemented?
You can bet your ass it is not going to be with policies and laws. The Government is not going to do anything. It is going be up to the individual. The Government will side with the muslims. Christians and Conservatives are the only ones that the Government will fight. So you are on your own.
