I'm not the man to ask about offensive terms because it seems I don't know the correct answer and I don't want to offend anyone. But the math can't lie. Black people are ~13% of the population and holy crap would I love to have all of them on pro-gun policies.
Most of our "gun control" historically was targeted at minority communities and this was the racist invention of "may issue" gun permits.
This is why I volunteer for helping instruct women and the Pink Pistols (a gay gun organization). We don't care about your race, gender, or creed as long as you can be safe and have fun at the range. I want the most amount of Americans to be comfortable using a firearm whether that means self defense or just a fun range day. I actually consider it a safety requirement because America has more guns than people so knowing how to be safe when you find a gun is a big deal. The Eddie Eagle policy of "tell an adult" only works if the adult is competent. And we all should be. It's right up there with defensive driving and how to use a fire extinguisher.
