Tamils dont care who ram is, he is not their god, ram is the god of Hindus. Its the Aryan Brahmanist sanskrit texts, that have mentioned ram's ancestors as Tamils.
Arent these smriti sources valid and considered authoritative in Hinduism. If you reject the smriti , then you need to reject Hinduism. This you can do in your own capacity but no bonafide Hindu leader/scholars will reject the sruti/smriti texts
Tamil religious sources (e.g Dravida Vedas) are only authoritative to Tamil religion, not to Hinduism. Dont confuse the 2 different religious systems.
Srimad Bhagavatam - Canto 9 , source :
https://prabhupadabooks.com/sb/9/1/2-3?d=1
yo ’sau satyavrato nāma
rājarṣir draviḍeśvaraḥ
jñānaṁ yo ’tīta-kalpānte
lebhe puruṣa-sevayā
Satyavrata, the
saintly king of Draviḍadeśa who received spiritual knowledge at the end of the last millennium by the grace of the Supreme, later became
Vaivasvata Manu, the son of
Vivasvān, in the next
manvantara [period of
Manu]. I have received this knowledge from you. I also understand that such kings as
Ikṣvāku were his sons, as you have already explained.
According to Matysa Purana the story is :
According to the Matsya Purana, the king of
pre-ancient Dravida and a devotee of Vishnu, Satyavrata who later was known as Manu was washing his hands in a river when a little fish swam into his hands and pleaded with him to save its life

What language ram spoke is not the matter of contention. Sanskri text were written much later (probably written between 500 and 200 B.C).
ram is insignificant to Tamils, theres no significant religious works or temples on/for ram in Tamilnadu. Exception being Tamilnadu born ram's Thiagaraja's Telugu ram kritis (hymns) and kamban's Tamil translation of valmiki ramayan.
The major Tamil religious hymns/works are in praise of Tamil gods Siva, Murugan and Vishnu. However, ram is Hindutva (Hindi-Hindu-Hindustan) god of Hindu nationalism
Language vs Race, many 3rd gen NRI kids dont speak Indian langauges, apply the same logic to ram i.e if you have solid evidence that a 7000 yr character spoke the 3000 yrs old imported langauge -
Are rejecting the smiti evidence of ram Tamil (dravidian) root ?

See diagram below, ram solar dynasty traces its lineage to Manu, Dasaratha is in 63 position followed by ram.
As per Aryan Sanksrit texts (Srimad Bhagavatam and Matsysa purans), he was a Tamil king saved from the great deluge by Vishnu's fish incarnation. This tallies with Tamil sangam sources on Kumari Kandam submergence.
Bhagavad Gita Chapter 4 text 1
sri-bhagavan uvaca
imam vivasvate yogam
proktavan aham avyayam
vivasvan manave praha
manur iksvakave 'bravit
TRANSLATION
The Blessed Lord said: I instructed this imperishable science of yoga to the sun-god, Vivasvan, and Vivasva
n instructed it to Manu, the father of mankind, and Manu in turn instructed it to Iksvaku.
Hindu religion (imperishable science of yoga) owes its existence to Tamils via Manu, the father of mankind. Its secondary whether the language of their text is sanksrit or they didnt speak Tamil, the primary source of Hindu religion is Tamil.
ram worshiping the sun dynasty's patron god - Ranganatha (or Vishnu) who is is Tamilnadu (ever wondered why ?)
