The first one is saying Nair and Namboodthiri, both aare matriarchal, which is not the case. Namboothiri, the Kerala Brahmin follows Patriarchism.
The second one is saying Guruvayoorappan is an avatar of Lord Krishna. He is not considered as avtar of Krishna, but Krishna himself, more specifically Krishna as an infant.
And the third is Ravi saying the whole issue is because he is of backward caste Ezhava. The issue was his wife being Christian and Hindu Temples in Kerala does'nt allow non hindus to enter temple premises.
So his son was not considered a Hindu because his mother was Christian.
Ravi has every right to feel aggrieved but being a responsibe citizen and a leader of status he should not distort facts ang give it a casteist colour. Especially in Kerala's background where casteism is not at all prevelant.
