"Constitutional Rights" is really a misnomer. The US Constitution gives no one any rights. The Constitution is a document charging the government with a few responsibilities and the power to discharge only those responsibilities. As the Declaration of Independence stated, The People will form a government to protect the rights they have been endowed by their creator. The Constitution is the document forming that government.
The so called "Bill of Rights," is the first ten amendments to the Constitution. However, it does not convey any right to anyone. These amendments prohibit the government from abridging, infringing, or violating rights We the People already have. The ninth amendment goes so far as to prohibit the government from denying or disparaging The People's other rights just because they are not specifically mentioned in the Constitution.
All rights are The People's. The government has the responsibility to protect them.
