This "Tantri" has contradicted himself on many occasions. For eg: he said in the interview that he is following the Guruvayoor Devaswam act. This act says all Hindus should be allowed into the temple. A followup act assigns the religion of the FATHER as the default religion of the child unless the child has been accepted into another faith. So by all definitions, as per the law of the land, Shri Ravikrishna is a Hindu and the "Tantri" must consider him as such. The "Tantri" on one hand says that he will follow the law of the land, on the other hand he says he is not bound by it as his word is the law within the temple premises.
Read the interview again. He states clearly that Devdasam act bestoes him rights to become supreme in terms of religious rituals. And he is performing that as his duty!
As far as who is Hindu, he clearly stated law which got changed 30 years back , effects ONLY Property, other rights. IT CANNOT TOUCH RELIGIOUS RIGHTS!
Period.
CPIM knows it will bite dust in the court. So, they are using these propaganda to derive caste mileage out of this. Plus, there are many minorities who appreciate CPIM;s histility to Hindus.
