Sorry for the late reply.
Last two weeks I have been travelling and visiting ancient temples in Tamil Nadu. The ones in villages and small towns. 3 of these temples have a hero stone (proclaiming the glory of the king who built the temple and bestowed it agriculture lands for its maintenance. The Hero stones date 1 of the temple to 8th Century CE (2813) years to be precise The language of the inscription is P Proto Sanskrit and the script it is written is Brahmi. This was a Vishnu (Perumal) temple.
Similar was other two which had 10th century CE hero stones but they had Tamil inscriptions in Brahmi Script
Just two points
Sanskrit and Tamil existed and proliferated together and even shared a common script Brahmi.
people are just being ridiculous idiots fighting over Hindi and Other regional languages in tweets and posts that are in English. And they really are unable to see the irony in that.
About Asur.
Names Sura and Asura rose to prominence on account of the Samudra Manthana episode
Sura is another name for wine though in rigvedic context it is used colloquially for Soma/ Amrita . Consumer of Sura were Devas. 
Rigvedic epithets for Indra and other Devas is the drinker of Sura
sUra (Pronounced as Shura) means brave. Term Asura/sura have no connection to Shura or bravery
 Asura are the ones who did not drink sura
Asura does not mean evil or demons
similarly Danava Daitya and Rakshasa also does not mean evil
Danava is matronym. Name derived from mother’s name
Like Pritha’s sons were called Partha or Radha’s Radheya
similarly sons of Danu (Rishi Kashyap’s third wife Danu) were called Danava
Sons of Diti (Rishi Kashyap’s second wife Diti) were called Daitya
Sons of Raksha grandson of Diti who saved his mother’s life (Diti’s daughter in law) when she was pregnant from her womb were given the surname Rakshas
similarly Adityas (Indra Surya and rest of the 10 brothers) are all called Aditya for being Aditi (Kashyap’s first wife Aditi) sons
During Samudra Manthan Aditya boys got the Sura with Mohini (Vishnu avatar) help and Diti Danu and Raksha’s sons were denied it ( Basically Adityas appointed as royalty or rulers of three worlds and their step brothers were denied it)
so Adityas became popular as Sura the wine drinkers and their step brothers as Asura the one who did not get to drink wine.
