Do not consider Collectivists as "sincere but deluded idealists". The proposal to enslave some men for the sake of others is not an ideal; brutality is not "idealistic," no matter what its purpose. Do not ever say that the desire to "do good" by force is a good motive. Neither power-lust nor stupidity are good motives.
Ayn RandThe only proper purpose of a government is to protect man's rights, which means: to protect him from physical violence. A proper government is only a policeman, acting as an agent of man's self-defense, and, as such, may only resort to force only against those who start the use of force.
Ayn Rand
