As for Arundhati, Fred said "almost ended with a Goan connection." As far as I know and it has not been denied by both parties, she was married to a Goan, an up and coming architect then, Gerard da Cunha. She lived in Goa, and perhaps taught aerobics. Don't know for sure (maybe Google can help but that's Fred's forte 😂)
The Dalits have different view of Gandhi, and I was given a photocopied book (forget the name), written by a Dalit, in which Gandhi was slammed. I think the book circulated underground among well-known Dalits, and this person was in charge of Dalit movement in Canada and has now gone to work at the UN.
I have seen the short film, Jai Bhim Comrade, by the famous documentary maker Anand Patwardhan. I also had a long interview with him when he came for the Toronto Film Festival many years. No doubt Anand is left-leaning, it brought out the atrocities faced by the Dalit community.
Anand also made the remarkable short film, Ram ke Naam (In the Name of Goa), a runaway success among the "subaltern" (Fred's favourite word) people. Anand is more faithful to the cause of Dalits and has is more accepted by them.
Arundhati's heart may not lie with the Dalits, but she's there to espouse causes that has social impact. Her fame gives her licence but I don't think the Dalits care much for what she says. They have their own people to carry forward the community's cause.
When the Dalits rose, sort of in arms, in Mumbai in the 70s, the showed they were united in their fight for equality and social mobility. I watched many of them saying lot of things.
As for Gandhi, one can't put him into a bracket. As Augusto says, Gandhi was "complex". Having read his books and also books on him by foreign authors and seen the movie, Gandhi deserved to be immortalised. Whether one likes him or subscribes to his way of living and political thinking, Gandhi's Hinduism was much more to his religion and faith than Veer Sarvarkar.
One book I read Gandhi: Judith Brown, an internationally-known historian, who taught at Oxord and had the distinction of being born in India. She and many others have tried to pierce the soul of Gandhi and none seem to be able to pigeon-hole him.
If today, Gandhi is assailed by the far-right wing of the BJP and feel that Nathuram Godse did well by getting rid of him, there's a conspicuous attempt by this group with the Hinduvta brigade to smear Gandhi's name. The politics of British India and in the context of the nationalist movement need to be looked different than the present times. For some, Gandhi may be relevant till today and for some he's a relic of he past.
