Technically, the whole anthem needs to be changed to avoid "outraging" people. For example:
"Our Home and native land" - technically, it belongs to Natives so it really isn't ours. And what about immigrants who weren't born here at all. Oh, the outrage!
"all thy sons command" - oh the outrage, THE OUTRAGE!
"God, keep our land" - a total dismissal of those that don't pray to any God or a God that goes by a different name. I can hear the tears flowing from the outraged people.
Also, the anthem excludes those that are deaf so we risk outraging them simply by having music with it. And what about the mute? We are excluding them by merely having words.
In all seriousness, the only way we can make our anthem all inclusive, is to boil it down to a simple fart since it's the bodily function we can all do. Problem solved.
