JojosMom,
Thank you so very much for this link http://www.american-historama.org/1801-1828-evolution/star-spangled-banner-lyrics.htm
The 3rd verse "hireling and slave" DO NOT in any way refer to the black slaves. I like the interpretation in this website. Teachers can use this when teaching the anthem.
I , a legal immigrant from a communist country, am very grateful to this United States of America and respect the flag, the anthem, and the pledge of alligence.
Stomping on the flag and burning the flag makes my blood boil. To me, the flag is not just a piece of cloth. No country is perfect. The U. S. is a great country and I love living here.
