Why is the pledge of allegiance used in schools?

To show respect.

The Pledge is used on children as a form of indoctrination and social control,Everyday in their formative years, before innocent little children can start their day, they must observe a religio-military ceremony promising to support America and God..

All through their schooling Over and over again, day after day year after year they recite the pledge,as with all indoctrinations (brain washing) if it said enough they will believe it and follow it without question..

Let us not forget the original Salute that went with the pledge,The Bellamy Salute was devised by Francis Bellamy, who wrote The Pledge.In the original salute the right hand is extended gracefully, palm upward, toward the Flag, and remains in this gesture till the end of the affirmation; whereupon all hands immediately drop to the side.

Up to WWII, American kids saluted during The Pledge, but this was type of salute was dropped when the Nazis adopted an extremely similar salute to their Furor Adolph Hitler.
