Periyar E.v. Ramasamy said this quote

When the purpose of clearly exposing the differences between the Aryan and the Tamil culture, civilization, conduct and creed Thirukkural was written. I am of that firm view.

~ Periyar E.v. Ramasamy

Man treats woman as his own property and not as being capable of feelings, like himself. The way man treats women is much worse than the way landlords treat servants and the high-caste treat the low-caste. These treat them so demeaningly only in situations mutually affecting them; but men treat cruelly and as slaves, from their birth till death.

~ Periyar E.v. Ramasamy

The terms `Husband' and `Wife' are inappropriate. They are only companions ad partners. One does not slave for other. They both have equal status.

~ Periyar E.v. Ramasamy

If god is the root cause for our degradation destroy that god. If it is religion destroy it. If it is Manu Darma, Gita, or any other Mythology (Purana), burn them to ashes. If it is temple, tank, or festival, boycott them. Finally if it is our politics, come forward to declare it openly.
