Periyar was a siriyar in thoughts .his thoughyts were different but spoiled the society as whole.he had no ethos.he was a hypocrite trying to change ,but more he preached anti brahminism more inclined people became to the same.what effect he made on the society except a herd of black sheeps like veeramani's.it helps the vote bank of the so called dravidian politicians.like karunanidhi.but karunanidhi is intelligent enough that he and his coterie used the periyar idelogy for vote bank and captured the media business for his family bank
