hindutva as defined by savarkar baguely means indian nationalism that draws its 'inspiration' from hindu maratha culture it cant be called hindu extremism is broadest sense largely since hindu fundamentalism is an oxymoron moreover founding fathers of hindutva were agnostic hindus hindutva rose as a complementary movement to marathi cultural resurgence all founders were marathis specifically marathas and konkanastha brahmins and till 's most memebers of rss were marathis hindutva in these days is a vague ideology it differs from one propounded by savarkar to the one practised by 'parties' like shiv sena and bajrang dal btw i was an active hss member till about before i left hindutva for good
