Left or leftism

Refer to the article ‘Left or Leftism’, DE April 8, 2018.
An excellent article .But I am sure the leftists are too arrogant to learn anything, otherwise, they would not have been reduced to such a sorry state and not become irrelevant. Their decline started the day they decided to hang on to the coattail of Congress and other regional parties to come to power directly or intellectually through them. They compromised for power, and in the process forgot their own ideology. Their only aim or objective remained to oppose nationalism. They had to and would continue to pay the price by becoming irrelevant and ultimately extinct in India.
