Left and Mamata are both sides of the coin. The present mamta's agitation has valid reason but these Lefts (specially CPM) are like Dog. Dog will not eat and let others to eat. That is their policy. Their laboratory is in Kerala & W/Bengal. They succefully experimented this theory to these states for the last 30 years. They always want supporters as un- educated/backward for their zindabad. So un necessary hue and cry for the Mamta's agitation is a time waste for all of us. This is a great lesson for Prakash and company
