I think you might have not read about Dr. B R Ambedkar. Then definately Phule Shahu are out of ur reach. Sadly but truth, many people do know about caste system n that it's disgusting too , but less did they know about the battles, sacrifices revolutionaries and the people had paid and have been paying to liberate from this hell. No one loves to be slaves. No one love to live in hell. It's not ur fault though since the real history has always been manipulated and hided . But guys Half knowledge is dangerous. You should go through "Annihilation of Caste " by BR.Ambedkar and should read about the solution rather than disgusting the matter . I am sure if you do so you will get ur answers. Lastly do check out this person Dr.Ambedhkar . I suggest you to read more . 🙏 Namo buddhay.
