In the late sixties and early seventies, CPIM used to organise atleast one bandh in a month. It was like menses for ladies. It comes definitely once in a month - may not be exactly on the same date. And durinv every Bandh, at least a couple of congresmen used to be murdered. In retaliation congressmen also used to kill CITU workers. There are lot of martyors memorial although out Kerala. Now these two parties although fight each other in elections, sit together in the parliament. The souls of all those who died in these clashes, will never pardon both CPIM and congress for the opportunist alliance they have formed now in the name of keeping comunal BJP away from power. In fact, CPIM is the most communal party in India, having paved way for a separate district for muslim in Kerala.
