Ashoka converted to Buddhism and ruled almost the whole of the Indian subcontinent at one point. But that doesn't mean he converted all Hindus to Buddhist. Few Hindus may have converted, but 'land of Buddha' also happens to be the 'land of Sanatana Dharma' where there are several other deities people worshiped and traditions people practiced.
Looks like you deep rooted anti-semitic hatred for Brahmins more than anything else.
> No present day Hindu remembers or honors Buddha or his teachings.
Well I do ! In fact some of the greatest Hindu philosophers spent their lifetime studying Buddhism and writing books. Even the Vipassana teachers in USA and everywhere happen to be Hindus not Buddhists.
> If purpose was to absorb his teachings, the caste system is still present.
Buddha himself was a proponent of basic tenants of caste. Buddha primarily took Brahmins as his disciples. Nearly 40% of his students where Brahmin and nearly all who got popular and wrote about buddhism were Brahmins. Buddha's multiple childhood friends studied at Takshashika a Hindu university that existed before Buddha and later prominent Hindu Brahmins like Aryabhatta studied at Buddhist universities like Nalanda.
When the Shakya king decides to disown his wife because she was born to a low caste mother, Buddha stops him, not by citing that "caste is evil" but rather the well established Hindu rules of caste that it is father's caste that should matter and not that of mother. Not to mention Buddha also predicted the future Buddha to be "maitreya" a person born in Brahmin family.
Even on the matter of "caste", Buddha is pretty much a Hindu.
