Absolutely. Because the Tamils and Arabs needed each other as trading partners at the turn of last millenium, and the Tamils were already militant (as Dravidians), instead of being exterminated by them like the northern Indians were, the Tamils absorbed the Arabs and just ate Islam up.
That is why Hitlers like Prabakaran, Arafat, and Thaci (and undoubtedly, the actual Hitler) are so hugely popular among Tamils today.
