I am (just barely) old enough to remember the Black Panthers in the 1960s, when a group of black people tried to carry legal firearms to protect themselves, before they were mostly murdered by the police, the FBI, and one another.
I also remember the 1980s, when the NRA was trying to convince all marginalized groups (blacks, women, lesbians, gays, socialists, etc.), that arming themselves was a great idea. The NRA was sincere, I think—they just wanted more people to have guns.
Most people, especially black people, were well aware of the fact that walking around armed would make it much more likely that they’d be killed by the police. (They remembered what happened to the Black Panthers, presumably better than I did.)
Over the last couple of years, and especially over the last few days, I think perspectives are changing. First, a lot of white people are walking around armed, and even killing people, with minimal consequences. Second, the increasingly fascist police have been killing unarmed people at increasing rates, and looking like they’ll not only get away with it, but looking like they’re glorying in it.
There are definitely some black people thinking once again that being armed is a good idea. I hope they’re not horribly wrong about that.
