Learning about ideology is important for everyone, especially for the young people as potential agent of change. there will be a time when they will replace the older generation, the crucial time as they need to make a lot of public policies requiring serious and deep thought.
ideology enables people to think clearly and in argumentative way instead of talking emotionally. think of demonstrants who never learn about any ideology, chances are they will end up with blank slogan which only them and God know the hidden meaning. so let them talk two.
i wonder why we dont educate ourselves and our young people with ideology. it can fight againts narrow mindness, ignorance or even hedonism because there you can find philosophical thought which makes people become more mature.
