Can you link to the part of the Constitution that mentions turbans?
Are you really a low information voter?
The Constitution of the United States was written on four sheets of parchment. If you count the Preamble and all 27 Amendments (remember there were originally only ten), it comes out to 20 typed pages.
The IRS code is 70,000 pages.
Obamacare law is 2000 pages plus.
The Ombibus bill is 2000 pages plus.
Constitution in a mere 20 pages total, is obviously not designed to cover every detail of every rule and law. It is a broad guideline and focuses mainly on what federal government can not impose on the states and individual rights. It is idiotic to ask if Turbans are covered in the constitution.
