You should know that they have kept that poem for that long and they have not hidden it and that will remain there for ever. He used abusive language towards those who are looking after that poem
Communist ideology had not entered in the in the minds of those martyrs at that time and they made these sacrifices in the name of religion but remember in the Gadar movement there were Hindus and Muslims as well. And also they recited a poem before they got arrested in which they criticised those who were dividing people in the name of religion (read history of the movement) . And you should know that the leader of that movement Baba Sohan singh Bhakna joined communist party of india I am lucky that once I had the chance to see him speaking in Baba Bakala on the CPI conference
