People in Tamilnadu are used to this style of working of His Highness Karinanidhi. Normally he used to make Fun of Hindus. But, this time, as he is a big partner in Central Government, he thought himself as equal to God that he made fun of god by questioning his excistence.
He will never dare to talk ill about any gods. If he had spoken by this time, he would have been dead. He knows that. He will talk only about Hindus.
Hindus in Tamilnadu are a divided lot. He has brainwashed people based on castes / Aryan / Dravidian / OB / BC etc. He knows Hindus won't stand united and hence, he Hindu Hater is enjoying the fruits.
