Bloomberg:

Everybody's white. That's the conclusion from a survey of gun magazines I bought the other day. The survey, I admit, was not conducted in accord with the best research practices: I asked the guy at the subway kiosk for as many gun magazines as he could give me before the #4 train pulled in. He handed me three for $17.
All the magazines have ads for, well, guns, and loads of accessories (love the "Sneaky Pete" concealment holster). Naturally, they have stories on guns — whether "intimidating, big-muzzle looks" or a "Tank-tough Recon Tactical with added strength and reliability for patrol." In addition, there are features on gun life, such as columns in Guns Magazine called "Campfire Tales" and "Odd Angry Shot."
There are pictures of guys with guns, gals with guns, animals with guns, ammo with guns and guns with guns. Curiously absent are pictures of black people with guns, brown people with guns or Asian people with guns. The good guys are white. The bad guys are white. In the Gunworld depicted in these pages, pretty much everyone is white.

The magazine with the most blacks is Guns & Weapons, which has 2 (police officers, of course) out of 133 American civilians and cops holding guns. To be honest, I have no problem with blacks being underrepresented in these awful magazines.
