It’s still not our national anthem.
Every time we sing our anthem, we are memorializing the men and women who died to provide this nation to us. It reminds us of the eternal struggle to keep this nation free.
God is mentioned in the pledge, as well He should be.
Of course the real reason the wording was changed in the 1950s was so that kids would not misunderstand the phrase "one nation indivisible" as "one naked individual."
Or so I read somewhere...
