The wave of anti-sharia laws sweeping shall we say less enlightened US States such as Oklahoma address a non-existent threat-the numbers of Muslims in the US are not a sufficient number to engineer such a radical transformation in law and society. The number of Muslims in the states enacting these laws are even less.
They are also redundant. There are any number of Federal laws (not to mention the Constitution itself) preventing another form of legal system invading American jurisprudence and/or being used in its place.
These laws are a dog whistle for bigots and xenophobes….Like the Republican Southern strategy, the anti gay marriage campaign in 2004, and past busing and integration opposition, they are red meat in order to draw in voters, the lowest common denominator type of voter. For like Gay Americans and African Americans(not to mention the poor), Muslim Americans have become the whipping boy for religious Christian fanatics and Republican party trolls.
Beware when someone in America starts talking about state rights-wink, wink
