Eyes blinded and minds shut failing to see the reality
It was not social discrimination but social structure for a balanced society. However, these modern educated with an education system, which essentially arose from a Christian base, fail to see this part of the reality because their eyes are blinded and their minds are shut by an education system, which did not care for truth but for propagating a mission, beneath which lay the hidden motive of expansion of Christian imperialism.
Oh! That unfulfilled wish...
These Christian societies and our ChristianizedHindu society, which now dutifully apes its Christian counterpart, is rife with social insecurity issues of the magnitude that were unknown in those days of Hindu society. And yet, it is ChristianizedHindus who are pretty much vocal about this alleged discrimination in the Hindu society in the name of Varn system, probably because their only wish to be born with white skin has not been fulfilled.
What Islam could not do...
Islam could not destroy Hinduism in thousand-year1 but Christianity has done it, in large measure, within 170 years! This is the greatest contribution (or, Curse?) of ChristianEnglish education system in India.
