I could care less about the oppressive religion of Islam. It is the supremacist political philosophy of Islam that bothers me.
Is it Indian muslims who wear turbans or do some Hindus wear them too?
And it is disturbing that in the light of no motive it is assumed to be a hate crime. Sometimes a cigar is just a cigar. Sounds like a CAIR-like propaganda effort.
Indians who wear turbans are, by and large, neither Hindus nor Muslims, but Sikhs.
Sikhism, as I understand it, has a variety of life-vows the believers can take, the most basic and commonly taken--Khalsa--involves distinctive dress as well as undertaking certain moral/ascetic practices. (The others involve additional moral/ascetic practices.) For men, the distinctive dress includes wearing a turban, and for both men and women, not cutting their hair or beard. (My daughter's best friend at college is a Sikh.)
If you see a man with a really long beard, and a turban, tied in such a way that the edge along the forehead has a peak in the center, he's almost certainly at Sikh. If you see a man with a short, or obviously trimmed beard, or shaved mustache and beard, with a turban tied so the edge along his forehead is horizonatal, he's almost certainly a Muslim (and probability a Shi'ite, though not necessarily).
