This is a frustrating and arrogant thing to say. If you can honestly go through and thoroughly criticize the core collective works of great socialist thinkers like Engels, Marx, Lenin, Bakunin, Kropotkin, Goldman and the uncountable thousands who have poured thousands of hours into tomes which are freely available online to study and understand, then you should do so. I would love to read this! You'd probably become a very famous person! But coming out gung ho and so arrogantly conclude that all these people, and all the hard work they have done in both theory and praxis is kaput without a very strong argument behind you is pointless and childish. It stifles conversation and is the reason discussing economic systems with people who don't understand them is an exercise in futility.
