Here's what I wrote in response to a similar question on PEN-L:
The data in my report do not relate to the Indian Right at all. Nor do I think the young chap with the Nazi shirt or those who designed the crossbars ad thought much about the politics of the symbols they chose. That was the interesting aspect to me. The crossbars and swastika (independently used as a Hindu religious symbol) are sort of fashionable symbols in current India. The swastika kid probably wanted to gain attention and provoke in a typical teenage sense, while the crossbars are probably one of the many symbols that identify the wearer with America and hence "coolness".
