I suspect it has more to do with what the parents listen to.
Your walking on the fightin' side of me
Runnin' down a way of life our fightin' men have fought and died to keep.
If you don't love it leave it let this song that I'm singin' be a warnin'
When your runnin' down our country man your walking on the fightin' side of me.
To all you country music bashers "I Am Proud To Be An American" is a country song.
