If you know your history, you will realize that its the communist who has killing political opponents as their Standard Operating Procedure. For the communist, killing and physical violence and bullying is their past, their present and their future.
Now since most of the christians and muslims vote along religious line, the communists can only bank on Hindu votes and speak of "secularism". and since the Kerala Sanghi's is the only one who can snatch away that vote bank by highlighting the real status of Hindus in kerala, most of them get killed by the communists.
The RSS only responds to this killing by killing the killers, since that is the ONLY way they can survive in Kerala. Otherwise, when the communists come to power, sanghi's get killed by both the police and communist goons.
So the next time you want to bracket "sanghi and commies" kill each other in the same line, take a second look and then a third look and THEN don't do it.
