Ya, outside of tamilnadu people hate the dravidian movement because it strengthens the tamils. They want tamils to be weak so that they can walk over them, which will never happen. Tamils are economically, politically and socially strong and tamilnadu has been crucial in forming govt. in the center. Tamils are pioneering the resistance against brahmin dominance in politics and political decisions centering and favoring brahmins. That's why many are angry of the dravidian movement
Karunanidhi has done a lot of Tamilnadu, he's one of the greatest politicians India has ever seen
