Well, no. It doesn’t. In fact, it fails to protect our rights from the authoritarian monstrosity that it created.
Yes, all of the extortion, harassment, terrorism, assault, murder and war-mongering done by the U.S. empire is carried out in the name of the “authority” that the Constitution supposedly granted to the federal “government.”
Therefore, the Constitution is the primary cause of ongoing and abundant violations of the individual rights of people living here now, not to mention the people who have been victimized and oppressed here over the last two centuries.
To revere the Constitution as “pro-freedom” and “pro-individual-rights,” when it created the thing that violates those rights, makes about as much sense as revering cancer for protecting the health of the people.
