Tamilnadu needs another Periyar

I have written before on the curse that is the caste 'system' in India. What is so outrageous is that caste-based discrimination is still practiced in Tamilnadu - one of the first places in India that woke up to fight this unacceptable 'practice'. The fight was led by 'Periyar' E.V.Ramasamy and was quite effective - up to a point. If you haven't noticed, most people in Tamilnadu (and many in the neighboring states as well) have long stopped using their 'traditional' family names (as they are usually caste-based), and instead use an initial - which is usually the first letter of one's father or husband. Today some people are starting to use their caste-name as their last name, such as 'Iyer'. But the irony in most caste-based discrimination in Tamilnadu is that it is practiced by non-Brahmins. This is the height of idiocy and lunacy. The Dravidian parties are busy with their own vote bank politics. To get rid of this system that has long lost whatever rationale it might have once had, I think Tamilnadu needs another Periyar and another clean-up job!
I was reminded of the situation because of the recent news reports of a 'wall' that was meant to separate people belonging to different castes in a village in Tamilnadu.
