Hi! Have you ever met a Hindu from Louisiana?
Why do you say Louisiana? Don't you know that Hindu is a geographical, cultural, and later religious identifier for people indigenous to South Asia?
Because there is a substantial concentration of South Asian immigrants in the southern US! 
I see. If i get you right, SOuthern US has inhabitants from sub-Himalayan SAARC countries and, for some authorities, adjoining countries to the west and east.
Yes. So working on the assumption that Sikhs have established temples and compounds in Texas, I'd guess Hindus have done so as well in neighboring states - like Louisiana. 
I have seen some of their temples around. I learnt few things about the religion and i know the  fundamental beliefs of Sikhism, articulated in the sacred scripture "Guru Granth Sahib", include constant spiritual meditation of God's name, being guided by the Guru 
I agree. It's also interesting observing their respect for the natural state of the human body. They avoid cutting their hair and exposing it as that's an extension of their body
With what you just told me, i can see the reason why it is a religion that originated in the Punjab region of the Indian subcontinent. It all started  about the end of the 15th century.
I've personally met a few Sikhs, but the ones I've met aren't from Punjab, but from Delhi. They consider themselves to be less restrictive in their practices than those from the rural areas of India
Does that mean those in the rural has more believes. I know sikhs is one of the  youngest of the major world religions.
