PC Gun Battle

I am just returning from a nice vacation to Las Vegas. Among our many activities was a visit to an indoor shooting range. After selecting a weapon, a Glock for me, we had a choice of targets. There were basically three types of targets/bad guys to shoot at: Arab/terrorist ( sold out), white men, or Zombies. No blacks, Hispanics, women, apparent homosexuals, handicapped etc... villains to shoot at. Most of the many customers were white. How could a business get away with portraying their customer base as villains to shoot at?
