Honestly you can claim that about everything. Stop signs contribute to a culture of violence for their Red-Yellow-Green color denomination create subconscious relations within peoples minds, thus contributing to a atmosphere to violent xenophobia against Native Americans and Asians due to classic color associations with the two races.

See? What I posted up there was pure nonsense. Absolute gibberish. But, if I just claim I'm not talking about Traffic Lights making people racist, and instead assert that Traffic Light colors contribute to a culture of racism, suddenly I'm apparently legitimate in my critique, even though its a distinction without a difference.
