India is a plural democracy by Constitution with the notion of the nation state at the core of its foundation.
Any political party that do not believe in this plural democracy of India (Communists seek to establish autocracy "worker dictatorship") or do not believe in the separate national identity of India (Communist seek to establish world wide single autocratic state, hence they welcomed Chinese invasion in 1962) thus must be banned in India (being anti constitutional).
So the natural solution seems to be to BAN all sort of communist ideologies, groups and political parties.
