Bullshit. You said that as the Muslim population increases, there will be more Muslims in the government and eventually Sharia Law would be part of society.
That is correct.
Our society and the Constitution are both dynamic and fluid.....not static.
That's why we have added a couple of dozen Amendments to our Constitution over the last two centuries. Things like women's suffrage and the abolishment of slavery. (both of which were European ideas)
My thesis is that as the muslim population increases and they become a large voting block. Politicians will champion their issues in order to garner their votes. And muslims will be able to influence the courts, laws, and political process.
That's how America works........
