Islam and Brotherhood v/s Casteism of the Hinduism

When the Hindus will learn this manner of Brotherhood ? I think there is no such chance. Distance, Contempt and Segregation are the fundamental principles of the Hinduism. See 1. The Brahmins look down upon A Khatriya B Vaishyas C Shudras . 2 Then the same Khatriyas who were object of contempt by Brahmins, imitate the Brahmins and condemn A Vaishyas B Shudras , now see the fun 3. The Vaishyas hate those below them , the Shudras called OBCs. Now the fireball has come on the head of the Shudras, so they divided themselves in number of castes and sub castes and imitated casteism in their own fold. But the Kshatriyas and Shudras of decades back between 1871 and 1931 were bold enough to challenge this atrocious , inhuman caste system and embraced Islam in lakhs and changed the course of History and Geography. Yet the Hindus are not reforming themselves and their religion and are waiting for another wave of such mass conversions.Then there will not remain any need for change !
