I know a group of people who are like that today.
IIRC, the overly simplistic makeup of India is Aryans and Dravidians, the former being lighter skinned and mostly Brahmin/Kshatriya and the latter being darker skinned and mostly Vaisha/Shudra. It might be interesting to know how many of each group populates the vast horde of H1B.
The arrogant Brahmin’s are those polluting America and Canada
That is actually wrong, not overly simplistic
indians - or rather ALL South Asians (Afghans, Pakistanis, Indians, Sri Lankans, Bangladeshis, Nepalese, Maldivians and to some extent Bhutanese) are an admixture of:
Brahmins do have percentage-wise "more" Aryan genes, but Kshatriya and Vishya have Aryan genes too. Shudras tend to have closer to zero, but then they don't have much Dravidian genes either, but the older "sentinelese"
some Kshatriya are actually Kushans (Tocharians) like the Rajputs or other warrior groups that got assimilated into the Indic 'system'
As to the skin color - you are mostly correct, but it is, as you said, simplistic
