No it isn't.
14th. Sect 1
Section 1. All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
Clear as fine cut crystal.
I am a "gun nut". I've read the Constitution. I understand the basic philosophical points the Founders were operating under. I've even read the Papers, Debates, and the actual text of the legislation in question itself where I can find it. Their "fear" is entirely artificial and comes from the last couple of decades of liberal gun grabbers and their leftist media cohorts demonizing the entire "gun culture".
That's their problem and in no way minimizes my Rights.
The why did it take almost 60 years for anyone to realize that? There are still many, many people who feel that the "incorporation" angle is faulty and overreaching.
Again, if the Bill of Rights are considered to be limitations only upon the federal government, then how could they be considered "privileges or immunities of citizens of the United States"?
The SCOTUS doesn't even see it the way you do and instead use the approach that some liberties are so essential that they must be protected under due process of law.
To be clear, I want the Bill of Rights to be applied to the states - I'm just living in reality though and know that Barron v Baltimore is still in play and that it must either be overturned (not likely) or gone around via 14th amendment incorporation.
