I guess it shouldn't, but it surprises me no end that so many Westerners only think of swastikas in connection with Nazi Germany. Hitler, I think, thought it was some mythical Aryan symbol. And as any Indian schoolchild knows, the Aryans came to India. [In fact, many 19th century Hindu reformers started referring to the main religion of India as the Aryadharama] Wikipedia is quite expansive on the various uses of the symbol.
And with Diwali this week, one will see swastiks everywhere in India, as this photo shows. [Image from the Times of India website.]
