No role playing involved, I just shoot the things every so often.
I never did like round targets. I prefer silhouette or photo types, both because they help me practice targeting specific anatomical parts, and also because of studies on the reluctance of shooters to shoot at humans. Note that the military uses human silhouette type targets; there is a reason for that.
Overt racism is something else, entirely.
I do not oppose the OP's store owner's right to express himself, and in fact would oppose government sanctions against such speech. But, I would not give him my business, and I might give him a piece of my mind. (Cliche though it may be, my dad's best friend from his Navy days was black; racism was not tolerated in my home. Freedoms of thought and speech, however, were championed.)
