Why Do People Support The Pledge of Allegiance?
The pledge of allegiance was written by Francis Bellamy.
Francis Bellamy supported what he called "military socialism" which was a forerunner of "national socialism" and "fascism". The salute he had used in the pledge came to be used by Hitler. The salute was changed because of this but the pledge remains.
Most debate is over whether we should have "under god" in the pledge. People should really be complaining that we have the pledge at all.
We don't need fascist loyalty oaths to be free!
Of course if you just look at wikipedia it's not going to say everything.

"In "the children of the States are marshaled and marching" Bellamy foreshadows his desire for government schools to be indoctrination centers for the "Industrial Army" (a Bellamy phrase) explicitly modeled on the military and described in the totalitarian socialist novel Looking Backward by Edward Bellamy, his cousin and cohort."
(Personally I think calling these people socialists is as absurd as calling fascists or nazis socialists but that is what they called themselves. The important point is that the pledge was written by a man who promoted totalitarianism)
