I'm also not into pol sc. But I don't think I need to learn Carl Marx to understand basic things like 'Killing people is bad.' Wouldn't you have a different version of statements if you had anybody in your family affected in any way by maoists in last 10 years. Would you be welcoming Prachanda with garlands now ?. Ask anybody from a family whose any member has been killed by maoists if they voted maoists. I don't think even that Communist Manifest anywhere recommends to kill people for the sake of uplifting the society (You'd better know coz u seem familiar with it). 

I don't consider not reading that one book is an ignorance at all. There are thousands of books on philosophy or economics lying around. They sound good to your ears. Learn books, but look beyond the hard covers. We have seen economics of communist countries around the world. They must have followed that Communist Manifesto to drive their economy. Don't u think so ?

P.S.  I am not stereotyped.
