You keep making that charge, which you know very well is false.
To claim that “NO ONE in Tamil Nadu has been treated brutally” is simply a denial of the facts. As I noted, tens of thousands of them have been extrajudicially murdered. But that’s apparently OK with you and your paymasters. In your Hindutva world, that doesn’t count as being treated brutally.
Tamils are not being treated well in Sri Lanka or in India. That is why they seek independence, so they can run their own affairs without being subjected to brutality. Apparently, you oppose that aspiration.
I know Tamil Nadu is as free as freedom gets in India. Because I spend more than a week every month in Tamil Nadu, in the semi-urban and rural areas and occasionally in the big cities, as part of my work. The only extra-judicial murders are in your mind. I don't subscribe to Hindutva. Actually I worship at a Jain temple. Not that there is much wrong with Hindutva.
And no - Tamils do not seek independence from India - maybe only in your ISI paymasters' mind.
