Siddhartha as subversive

I did not intend to further comment on Dr Sen's overrated polemics, however there were statements, some asserted boldly while some sneaked in, which deserve mention in posts.
One such, sneaked in the true way of progressive/secular clique (and referred in the title) is the oft repeated assertion that Buddhism was a rebellion against Hinduism (or Brahmanism) or even that Gautam's intention from the beginning was subversion of Sanatana Dharma.

The history of relationship between Buddhism and Sanatana Dharma is complicated.
There have been times when adherents of one faith have been hostile to other. And yet Buddhism and Hinduism shares majority of vocabulary and semantics. However it is utter ignorance (or malice) to assume that Buddhism was some sort of egalitarian movement or proletariat rebellion against Brahmans, for this meme reverses the sequence of history.

The reason that Sidhhartha attained state of Buddha was not because he intended to be a rebel, but because he was seeking wisdom and truth, not because he was a proto-marxist but because he sought the meaning and way of life. When he reached that state, it turned out to be at variance with Veda, he did not believe that Brahmins and Vedic sage have grasped the complete truth of the existence, that they had beholden the essence of the being. Also, he did not believe in Caturvarna, a rejection which followed from his basic premises. However Buddhism was never a radical egalitarian movement both in its outlook as well as composition. This is clear to all except to Neo-Buddhist, who are in fact really subverting the message of Buddhism by turning it into a medium of hatred and vitriol against Hinduism.

However he couldn't have considered Sanatana Dharma entirely devoid of merit, for what he taught resonated with Sanatan Dharma, this is the reason Buddhists and Hindus have gained from mutual exchange (which though not always cordial were constructive) over the age.

While propounding the tenets of Buddhism, Gautama was seeking to answer the mystery which has vexed mankind since its dawn. Therefore it is the greatest insult not only to spirit of Buddhism but also to human curiosity when Buddha is reduced to caricature of a noble hero avenging the suffering of masses.
