I’ve always thought “This Land” was just a song of good intentions and nationalism as well.
It’s not like they lyrics are “Your land is my land, my land is your land...” haha
I made a point to take each of my 3 kids to DC when they reached about age 10. As we saw the sights, I’d ask “Who owns this museum? Who owns this memorial? etc...”
By the end of the trip, they’d each roll their eyes at the question, responding: “We do dad. We own this.”
the author of the song “this land” was a commie and wrote it with that intention.
