And that is only part of the story
The Pledge was originally written by a man named Bellamy. He published it in a magazine for youth, sort of aimed at Scouting aged people. This was in 1898, IIRC.
He intended it to be a unifying pledge. This was in a time when the USA was still suffering from bitter resentments over the Civil War. Bellamy specifically meant it to be recited by youngsters from ANY republic, there was no mention of the USA or god. He fought the hijacking of his work, when the U.S. government took it and inserted USA, arguing that restricting it violated the basic spirit of his intentions of inclusivity. But to no avail.
He was dead by the 50s, but I'm sure he rolled over in his grave when the McCarthyism people added "under God" . They were intentionally making it yet more divisive.
They wanted to draw a line between "good people " and "godless commies ".
I despise the pledge because what it represents. It represents coopting a symbol of inclusivity and using it to lie.
