Teaching someone to love something, worship it, believe in it, etc, etc, is indoctrination.
Your confusing what the word means. Just because something is indoctrinated doesn't mean its bad.
Oh and indoctrination has nothing to do with political views. You can indoctrinate to any number of things. And you say that doing it to a person is indoctrination, but to a country isn't? Do explain why that is.
The act of indoctrinating, or the condition of being indoctrinated; instruction in the rudiments and principles of any science or system of belief
So the pledge is a belief system now is it? here I thought it was an oath to one's country all this time. Let me explain. political systems are principles of beliefs that people hold. Democrat, Republican, Communist, etc., etc, Where one can recite a pledge to a country that holds many beliefs it does not indoctrinate a person in a particular belief especially our pledge. If however a parent lets say loves. Joe Smith and Joe Smith happens to be running for President and is a member of the communist party and I am a parent that believes in him with children and teach my children through songs and books that they are to believe that I do that Joe Smiths views are the right ones and there are no other views accepted except Joe Smiths , then guess what I have done I have indoctrinated my children into the same views I have.
