I posted this in another thread. Let me post it here as well so that you could understand our surprise when Indians like you claim that they love Buddhism which is part of the Dharmic, Indic and Hindutva based faiths.
To lend legitimacy to their campaign against Buddhism, Brahminical texts included fierce strictures against Buddhists. Manu, in his Manusmriti, laid down that, ‘If a person touches a Buddhist […] he shall purify himself by having a bath.’ Aparaka ordained the same in his Smriti. Vradha Harit declared that entry into a Buddhist temple was a sin, which could only be expiated for by taking a ritual bath.
Chanakya, the author of Arthashastra, declared that, “When a person entertains in a dinner dedicated to gods and ancestors those who are Sakyas (Buddhists), Ajivikas, Shudras and exiled persons, a fine of one hundred panas shall be imposed on him.
The Brahannardiya Purana made it a principal sin for Brahmins to enter the house of a Buddhist even in times of great peril. The Vishnu Purana dubs the Buddha as Maha Moha or ‘the great seducer’. It further cautions against the ‘sin of conversing with Buddhists” and lays down that ‘those who merely talk to Buddhist ascetics shall be sent to hell.
Prakash, Buddh,in his book "Aspects of Indian History and Civilisation", Agra 1965, states that Nalanda was dDestroyed by Hindu zealots. He adds that, even after the Islamic invasions of India, Brahmanist bigotry and hatred for Buddhists was not subdued. According to Sharmasvamin, a Tibetan pilgrim who visited Bihar three decades after the invasion of Bakhtiaruddin Khilji in the 12th century, the biggest library at Nalanda was destroyed by Hindu mendicants who took advantage of the chaos produced by the invasion. He says that "they (Hindus) performed a Yajna, a fire sacrifice, and threw living embers and ashes from the sacrifice into the Buddhist temples. This produced a great conflagration which consumed Ratnabodhi, the nine-storeyed library of the Nalanda University".
According to the historian S. R. Goyal (author of A History of Indian Buddhism), the decline of Buddhism in India is the result of the hostility of the Hindu priestly caste of Brahmins. The Hindu ruler Shashanka of Gauda [Gaura in Bengali] (590–626) destroyed the Buddhist images and Bodhi Tree, under which Siddhartha Gautama (Buddha) is said to have achieved enlightenment. Pusyamitra Sunga (185 BC to 151 BCE) was hostile to Buddhism. He burned Sutras, Buddhist shrines, and massacred monks in large numbers.
