We must undo what has been done
In thinking on this topic I've realized that to solve a problem, we must properly diagnose it.
I suspect there are many reasons why blacks do not OC in as large of numbers as whites. I suspect chief among these is the preponderance of blacks who live in anti-RKBA States. Most others tend to live in nominally pro-RKBA States that have unfortunate histories of racist laws or practices that denied blacks the effective ability to own and carry guns. Clayton Cramer details this issue in his excellent essay,
"The Racist Roots of Gun Control."
For those who currently reside in States with this history of laws (the Old South, New York), the essay may be uncomfortable. I've yet to read of anyone providing any material refutation to the facts put forth or the conclusions drawn in it.
I expect that for many of us, gun ownership is a multi-generational matter. It is part of family history and culture. Even with the dramatic increase in gun ownership from the 1970s to today, how many here are 1st generation gun owners? How does that compare to the black community? So this is a barrier.
There is also the barrier of perception. There are groups in our nation (urbanites, for example) whose sole personal experience with guns is limited to the movies and perhaps a bad encounter with a criminal. Others enjoy personal experiences confirming that regular, decent, law abiding people own guns. Whether it is hunting, target shooting, collecting, or
lawfully carrying for self defense, we have had personal, accurate, positive exposure to gun ownership that certain demographics are less likely to have enjoyed. This is another barrier.
Both of these barriers are best overcome through personal experience. Take someone shooting.
But there is another big issue. Whether justified or not, it seems a fair number of blacks believe they are at risk of violence at the hands of police. Many seem to believe that carrying a gun is tantamount to painting a target on themselves, begging to get killed by a racist cop. Whether these feelings are justified or not matters far less than the fact that they exist. Feelings are often not rational. So reason won't change them.
Jim Crow gun laws disarmed blacks not by calling out race explicitly, but by playing on these fears. By outlawing concealed carry (except perhaps by discretionary permit that could be denied at will), blacks were effectively disarmed. Little old white ladies don't often get their purses searched and so remained free to carry a self-defense derringer discretely. Respectable white gentlemen might expect certain courtesies were they to be found with a gun that wasn't fully visible. They would also be perfectly free to OC without fear of harassment.
Bottom line? If you want to get more blacks to OC, maybe start with getting more of them to CC. In the growing number of Constitutional Carry States this doesn't even require a permit. In the vast majority of States that now issue permits to carry on a non-discriminatory basis, blacks can get permits on equal footing with whites, the poor on equal footing with the rich, the average on equal footing with the well connected.
Just as non-discriminatory permits have been a stepping stone for many States to move toward true constitutional carry, concealed carry (either via permit or permit-free) might well be an individual stepping stone for individuals (black, white, women, etc) who are not ready to take the plunge into carry a gun
and advertising to the whole world that they are carrying a gun.
