Story at Caravan: The Defeated

The Defeated a Story/Report at Caravan. The author, whose name has been withheld for security reasons, is a journalist in India.

Swarna’s hardest moment in the LTTE was the haircut. After a 10-day training at the Siruthai Puligal facility, all 20 girls of her batch were asked to form a line under the harsh sun. One by one, their heads were shaved. Symbolically, they were being sheared of their femininity, lest it cripple their readiness for war. Practically, it did what easily identifiable smocks in rehab facilities do: it prevented recruits, especially minors, from escaping back to their normal lives. Swarna went through the haircut ritual for the eight years that she was a fighter. Each time she bowed her head under the razor, it brought on a fatalistic impulse. She remembered that she had no identity but that of a combatant, no freedom to run if she ever let herself feel fear. Running her hand over her prickly scalp, Swarna felt like a part of something larger. It was a por (war), but she believed it was a porattam (a revolutionary struggle). In recognition of her commitment, she was one of the few batches of girls that were taught satellite technology, and she became a navigator for GPS-dependent weaponry.

Did not agree with this line, which is incorrect.

Next came a republican constitution that said the Sinhalese were the original inhabitants of the island, and that their greatest duty was to protect Buddhism.

The constitution absolutely does not say "Sinhalese were the original inhabitants".  Does not even mention Sinhalese.
Neither does it say "greatest duty was to protect Buddhism"; what it says

The Republic of Sri Lanka shall give to Buddhism the foremost place and accordingly it shall be the duty of the State to protect and foster the Buddha Sasana, while assuring to all religions the rights granted by Articles 10 and 14(1)(e)
