Historically speaking, India was once a Buddhist country. Buddhism was violently suppressed and eliminated by the caste based Brahmin kings. Is this what you are referring to when you are talking about - "religious wars in the past (and even the present) and that there was a sizeable effect of religious conversion on hardening of stance on culture in Hinduism is naive and ignoring a big problem."?
The Brahmins took over control with a caste based system - apparently still active in California. Over time the new Indian dynasties which arose after the 7th and 8th centuries tended to support the Brahmanical ideology and Hinduism, and this conversion proved decisive. These new dynasties, all of which supported Brahmanical Hinduism, include "the Karkotas and Pratiharas of the north, the Rashtrakutas of the Deccan, and the Pandyas and Pallavas of the south" (the Pala Dynasty is one sole exception to these). The persecution of Buddhism started as early as in life or soon after the death of King Ashoka (Gonandiya). D.N. Jha writes that according to Kashmiri texts dated to the 12th century, Ashoka's Son Jalauka was Shaivite and was responsible for the destruction of many Buddhist monasteries.[7] The story of Jalauka is essentially legendary, and no independent corroboration of the Kashmir tradition has been discovered.[8] Patanjali, a famous grammarian stated in his Mahabhashya that Brahmins and Sharamanas (Buddhists) were eternal enemies[9] With the emergence of Hindu rulers of the Gupta Empire, Hinduism saw major revivalism in the Indian subcontinent which challenged Buddhism which was at that time at its zenith. Even though the Gupta Empire was tolerant towards Buddhism and patronized Buddhist arts and religious institutions, Hindu revivalism generally became a major threat to Buddhism which led to its decline. A Buddhist illustrated palm-leaf manuscript from the Pala period (one of the earliest Indian illustrated manuscripts to survive in modern times) is preserved in University of Cambridge library. Composed in the year 1015, the manuscript contains a note from the year 1138 by a Buddhist believer called Karunavajra which indicates that without his efforts, the manuscript would have been destroyed during a political struggle for power. The note states that 'he rescued the 'Perfection of Wisdom, incomparable Mother of the Omniscient' from falling into the hands of unbelievers (who according to Camillo Formigatti were most probably people of Brahmanical affiliation).[10] In 1794 Jagat Singh, Dewan (minister) of Raja Chet Singh of Banaras began excavating two pre Ashokan era stupas at Sarnath for construction material. Dharmarajika stupa was completely demolished and only its foundation exists today while Dhamekh stupa incurred serious damage. During excavation, a green marble relic casket was discovered from Dharmarajika stupa which contained Buddha's ashes was subsequently thrown into the Ganges river by Jagat Singh according to his Hindu faith. The incident was reported by a British resident and timely action of British authorities saved Dhamekh Stupa from demolition.[11]
Omvedt states that while Buddhist institutions tended to be less involved in politics, Hindu brahmins provided numerous services for Indian royalty:
