As Ronald Reagan stated that Communism belongs on "the ash heap of history" as a political system, so does Sharia law.
Therefore, as we carefully screened to prohibit entry of communists into the U.S.A in the past, today it is lawful, and necessary, to screen out those who follow Sharia, and prohibit entry to anyone who is suspected of following or promoting any form of Sharia, as its tenets and/or practices are counter to The Constitution, and American values.
