I hear - and it sure looks like - these guys are Sikh.
The Sikhs I knew in college were incredibly smart, reliable, friendly, and all sorts of good. As a people, in general, their military record is outstanding. They don't try to force their religion on anyone ... and though there was the Golden Temple unpleasantness a quarter century ago that is working itself out - they are as a group an impressive people.
Bearded & turbaned or fully westernized - the Sikhs here in the USA that I have run into my whole life are a great addition to our national character - even when they aren't chewing light bulbs.
Oh - and this is another reason not to mess with South Carolina.
