I know the difference between Sikhs (religion) and Arabs (ethnicity), I only lumped them together because most Americans do not and the original poster mentioned "turbans", hence a number of violent attacks against Sikhs after 9/11 by rednecks who didn't understand the difference.

Remember when the Hillary Clinton campaign released a photo of Barack Obama wearing a (Somalian) turban? http://www.theguardian.com/world/2008/feb/26/barackobama.use...
