reference to Tamils as race in found in this Tamil nationalism song (you are no greater authority than the great Tamil nationalist poet - Bharthidasan)
எங்கள் வாழ்வும் எங்கள் வளமும்
மங்காத தமிழென்று சங்கே முழங்கு!
எங்கள் பகைவர் எங்கோ மறைந்தார்:
இங்குள்ள தமிழர்கள் ஒன்றாதல் கண்டே!
சிங்களஞ்சேர் தென்னாட்டு மக்கள்
தீராதி தீரரென் றூ தூது சங்கே!
பொங்கும் தமிழர்க் கின்னல் விளைத்தால்
சங்காரம் நிஜமெனச் சங்கே முழங்கு!
Our Lives and riches
Is our Tamil that never fades
Blow this aloud, our Conch-shell!
Our enemies went in to hiding
Seeing all Tamils unite together !
Born are we, the Tamils
Along with the Sun, Sky, the moon and Oceans..
With whom our Tamil was born unblurred !
Alert the unwise cowards..here comes the lions' herd!
Blow this too aloud, our Conch-shell!
Blow, that the Tamils of South Country and Lanka
All together are brave and rise in masses
And those who harm such turbulent Tamil
Are sure to meet their end in peril
Blow this too aloud, our Conch-shell!

Tamil racial reference in SInhala text (Mahavamsa)
The Victory Of Dutthagamani
Arrived at Mahiyangana[
7] he overpowered the Damila Chatta.
When he had slain the Damilas in that very place he came then to Ambatitthaka,[
8] which had a trench leading from the river, and (conquered) the Damila Titthamba; fighting the crafty[
9] and powerful foe for four months he (finally) overcame him by cunning,[
10] since he placed his mother in his view. When the mighty man marching thence down (the river) had conquered seven mighty Damila princes in one day and had established peace, he gave over the booty to his troops. Therefore is (the place) called Khemáráma.

Damila Maha Seya
Located on the Pollonanruwa ancient city complex, this gigantic uncompleted Stupa known as Damila Maha Seya (Demala Maha Seya) has been built by king Parakramabahu (1153-1186)
using the labor of Tamil (Damila) prisoners brought from India when he attacked the Soli Kingdom in South India.
