Carter and W both banned Muslims for awhile.
That may be partially true.
However, the notion of targetting an immigration ban on a religion, such as islam, has become politically radioactive.
Period.
A far more practical and effective way to reduce any new islamic threat coming to our shores would be to ban All immigration from high terrorism / crime risk countries including those that *subjugate women and gays.
Bingo - no more immigration from *islamic countries or high violence central American countries like Mexico, Honduras, El Salvador, etc.
We’ve got to be smart if we’re to have a chance to save our country and guarantee a free republic.
