This is a fact, undeniable. And don’t blame britishers, blame high class hindus, blame hindu scriptures
Really now
Let us see what the evidence says then shall we:
Lord Krishna as saying, in response to the question? “How is Varna (social order) determined?”
“Birth is not the cause, my friend; it is virtues which are the cause of auspiciousness. Even a candala observing the vow is considered a brahmana by the gods.”
“Of Brahmanas, Kshtriyas and Vaishyas, as also the Sudras, O Arjuna, the duties are distributed according to the qualities born of their own nature.” - Bhagavad Gita
“There is no superior caste. The Universe is the work of the Immense Being. The beings created by him were only divided into castes according to their aptitude.” - Mahabharata, Shanti Parva, 188 "
Says the Mahabharata, in the famous dialogue between Yudhishthira and the Yaksha:
?A man does not become a Brahman by the mere fact of his birth, not even by the acquisition of Vedic scholarship; it is good character alone that can make one a Brahman. He will be worse than a Shudra if his conduct is not in conformity with the rules of good behavior.?
Manu sums up their relative status and functions in society in the following verse:
?The Brahman acquires his status by his knowledge, the Kshatriya by his martial vigor; the Vaishya by wealth; and the Shudra by birth alone.?
Now isn’t it interesting that the most respected and powerful sages, kings etc are born Shudras?
Sage Vyasa, a Brahmin sage and the most revered author of the major Hindu scriptures, was the son of Satyavati, a low caste woman. Vyasa’s father, Sage Parasara, had fallen in love with Satyavati, a fisherwoman, and had married her. Vyasa’s deep knowledge of the Vedas later determined the caste of Vyasa as Brahmin sage, and not his birth to a low caste-woman.
Sage Valmiki, the celebrated author of of the epic, Ramayana, was a low caste hunter. He came to be known as a Brahmin sage on the basis of his profound knowledge of the scriptures and his authorship of the Ramayana.
Sage Aitareya, who wrote the Aitareya Upanishad and was born of a Shudra woman.
Rishi Parashar, the famous law-giver was the son of a Chandala, the lowest of the Sudras.
Rishi Vasishta was the son of a prostitute, but honored as a sage.
Sage Vidura, a Brahmin sage who gave religious instruction to Kind Dhritarashtra, was born to a low caste woman servant of the palace. His caste as a Brahmin sage was determined on the basis of his wisdom and knowledge of Dharma Shastras (scriptures).
The Kauravas and Pandavas were the descendants of Satyavati, a low caste fisher-woman, and the sons of Sage Vyasa. Vyasa’s father was the Brahmin Sage Parasara, the grandson of Sage Vasishtha. In spite of this mixed heredity, the Kauravas and Pandavas were known as Kshatriyas on the basis of their occupation.
Chandragupta Maurya was from the Muria tribe, which used to collect peacock (mor) feathers; Samrat Ashok was the son of a daasi.
Saint Thiruvalluvar who wrote Thirukural was only a weaver. Other saints were adored including Kabir, Sura Dasa, Ram Dasa and Tukaram came from the humblest class of Hindu society.
Funny that we see no evidence of this great oppression you talk about
