Communism once were defined by Stalinism, which is not very different from the Fas8ism/ Na8ism in which the RSS' ideology has its origin. Both are anti-individualistic doctinaire ideologies.
Both were evil. Only difference is that there is hope for the left because they have gradually turned into social democrats, similar to what has happened to the left in Europe, whereas RSS/ BJP is falling more and more into the likeness of their ideological progenitors.
And ha! RSS protecting Hinduism! its an Oxymoron. They do not understand Hinduism, and are bent on destroying its essence.
