Communism is the cancer of head with misery, disease and poverty as side effects.
Their biggest arsenal is their propaganda. Moreover, they're ruthless killers. They wouldn't hesitate to kill millions of people for sake of the rotten slave foreign ideology. Isolation of downtrodden and hopelessness are the breeding ground of these pests.
Development, free thinking, free media and education are their worst nightmare. As long as India keep helping their poor and there is hope for everyone, communism cancer cannot spread all over. As the free media and education is spreading, their tools of brain washing wouldn't work. All people have to see what's track record of communism is all over the world. We don't have to go to outside world. Nehru-clan's 50 years rule was in fact a shade less than communism.
It's everyone duty to see this cancer is rooted out of Indian society for the betterment of all citizens. I'm sure we'll see promising results in forthcoming elections on this front.
