The title refers to the Sangh Parivar.
Leela Samson is one of the country's top dancers. She is also the director of Kalakshetra, an art institution in Chennai that originated with the Theosophical Society and Rukmini Devi Arundale. And she happens to have Jewish-Catholic parents.
That is enough to make the saffron see red. That's a crowd that has, collectively, not contributed a fraction of a percent of what she has to Indian culture; that's a writer who exhibits his ignorance of Kalakshetra almost in every sentence, yet says he is "ashamed of the Samsons in our midst". A previous writer in that rag details her alleged anti-Hindu sins, such as removing the "restrictions on the meeting of boys and girls within the boys’ and girls’ hostels."
You thought the Taliban were the worst kind of fundamentalists? Just pray our homegrown variety don't take over our country.
Here's a better perspective on the current Kalakshetra fuss.
