What about two skinny rednecks? Would that make a difference?
If not, why make a reference to weight at all?
You may have meant no offense. You probably have just been programmed by the media to host stereotypical prejudices.
“What about two skinny rednecks? Would that make a difference?”
It may: If the skinny rednecks appear fit, then I may not attempt to wrestle the gun away and overpower them. But if I am a young fit guy and I am confronted by two obese men who appear to have the muscle tone of jelly and no stamina, then I may try to overpower them rather than run at the risk of getting shot in the back.
