Vedas do not have Caste Vedas do not tell a word on Caste, but a Passing reference on Varna in Purushaskuktham.

Varna System is clsassfication under the type of Profession held and it was not by Birth as per Vedas.

One Who Seves and God and does on behalf of Others with Vedas- Brahmins
One who serves King and Kingdom and can use Sword & Arms – Kshyatrias
One who does Agriculture or trade in Agri Goods is – Vysias
One who remain as helper for all the Three – Sutras
In Mathematics Formulae is translated as Sutrams and Sutras are not Untouchables and they can come up in to the Ladder by doing other works and I put these from Maxmuller through Gilbert Slater who all patronoised Dravidain mYTHS

Certainnly Casteism in Hinduism is not a Pleasant one and I quote GILBERT Slater- who gives from Maxmuller, and I Quote from Tamil Translation by PanmozhiPulavar Appadurai.

Now Tholkapiyam has in depth of Varna System. It denies Education to the Fourth, Fourth cannot enter trade at any time etc., Sangam Literature names many Sub-castes even such as “ Irular, Villiar, Pallar, Vettuvar, Aayar, barathavar, maravar, kuravar etc., Sangam Lit. mentions even Many Gotras of Brahmins such as “Kasiyaba, Vathula, Aathreya, Koutinya, Kousika” etc, and as per Vedic practice calling them “Twice Born” etc.,
A Friend in another Forum even gave the Etymology of Caste in Tamil Sathi:


//saar - saarthi - saathi - >>> jaati.

only tamil explains because it contains the root word "saar" or "chaar".

saarthi - saathi = saarnthathu.

saarthiyaar > saarnthavar. this phrase occurrs in tolkaapiyam.//

Any body taking a Athesitic stage can attack Old Literature, such as Kavignanar Kanimozi(Daughter of M.Karunanithi), who came in support of Freedom of Expression that Sangam Literature such as Kurnthogai and Narrinai has lot of Pre-martial Sexual relationships and Charu Nivedita supported this. Bible has extensive Racism even practiced by Jesus, but that is not discussed always but ..
We have a Pratice of Telling our Problems to Religion and Missionaries have taught like that Barahiar condemens it in his Short ARTICLE called Á¾¢ôÒ

So Vedas which as per Panmozi Arignanar Jaggannatha Raja- in his Book “Tamilum Pragiruthamum” published by TN Govts. International Tamil Studies- dated 5000-1000BCE, has much superior Science and Maths etc., is ignored.

Let us value Literaure for its positives please.
