All people are leftists by default when they are born But when you learn more about the world, read books, study politics, economics, psychology, logic, mathematics and so on you become right. Leftism is ignorance it can be cured, it can't be refuted. All your arguments a leftist would fail to understand. They don’t have your knowledge, they don’t have your experience. They view the world as a primitive construction, any problem for leftist can be solve be force, probably by shooting someone or by controlling production, forceful redistribution and so on.
