Call the school information office, Patti Caplan 1-410 313 6680 and ask her the name of the teacher who wrote the song with her class as an assignment, last year. Ask her about the purpose and how she thinks that this song meets that goal.
Let her know that this kind of indoctrination and hero worship is inappropriate in a public school.
I left a message informing her I would be sending an email. The email asked if there is any truth to this “Internet rumor.”
I do not expect a response before nightfall
