I do think there is something to what he says. It's changing because of dedicated efforts by the likes of the VHP, BJP and other associates parties but Hinduism has a tradition of being big tent and tolerant compared to other major religions.
- No religious figures - whether Muslim, Buddhist, Jain, Christian etc. are insulted
- All religions are allowed to carry out proselytization activities
- Multiple religions religious days and public holidays are accepted
It's what made Hinduism likable for non-religious folks but I do understand the viewpoint of the Hindutva types. If they continue to be endlessly accommodative, it's very possible Hinduism in India would end up like Christianity in Scandinavia. Present in theory but not practice. Religions like any other ideology are as much defined by their red lines and hates as much as their beliefs. By internal consensus, they've chosen to fight the red lines to be a ban on cow slaughter and reclaiming a few ancient temples. I accept that and thank my lucky stars they haven't chosen something like the caste system or widow remarriage which would be truly harmful to society.
