typical Hindutva anti Tamil 'punnakku' meant for cow belt sanghis consumption to justify Tamil genocide, formerly LTTE and Prabhakaran were branded as Christians now its Tamilnadu fishermen
What religion Tamils wish to follow or convert has nothing to do with Hindutva's or India or its Vatican conspiracy theory. Hindutva sanghis divide and rule tactic based on religion will not work in Tamilnadu.
Tamilnadu would not be encroaching in Lankan waters if India had not gifted katchatheevu to Lanka. If crossing international waters justifies killing of Tamilnadu fishermen , on religious grounds , it only exposes India's racist anti Tamil strategy - i.e annihilate Tamils working in tandem with its terrorist partner - Sinhalas.
Just ponder, if Tamilnadu is/was an independent state , Tamils will not have to suffer from occupying pseudo Aryan Indians /Sinhala, they would have their own navy to protect their citizens. Such blatant killing of Tamils never occurred when the Cholas or LTTE controlled the Indian ocean
Tamils have the right to fish in their traditional waters and oppose Indian projects (such as nuclear plants , methane extraction etc) where their livelihood and survival is at risk.
