You might be misunderstanding the comment, although I'm not 100% sure. I think the poster means that yes, gun control is elitist and discriminatory and that it is racist, too.

It was used in the past to deny blacks the right to bear arms, and from the video I saw that even in more recent times some localities can arbitrarily pick and choose who they want to allow to have a gun permit and that blacks have often been denied permits for no good reason while others get them.

Just like California and New York and Chicago etc do right now---only the very rich or important elites can have gun permits; NOBODY else can.

Ordinary decent black people who live in or near high crime areas cannot defend themselves against criminals in places that have gun bans. (Neither can anybody else for that matter) This creates what is called a 'disparate effect' on them, as people who do not live high crime areas suffer less violence and crime even though they too are unarmed.

Law abiding blacks today who are able to exercise their 2nd Amendment rights are just as concerned as anyone else that a bunch of communist leaning elitists want to disarm them.
