This crap has been going on for a long time. Remember the movie “How the West was Won”? Did you see it on TV or in the theater? If you saw it on TV you didn’t see the final scene

narrated by Spencer Tracy with scenes from modern day America as it was in the ‘60s.
I think it was in the ‘70s that Hollywood released the TV version with the last scene axed. Seems that by that time they no longer liked a healthy dose of patriotic Americanism.
I vaguely remember that movie.
I saw the movie when it came out in the theaters. I also saw it at least a couple of times on TV, and I remember having an odd feeling after seeing it on TV but couldn’t put my finger on it. Now I can. As far as the flag on the moon, I assume eight years of “you didn’t build that” and this country isn’t exceptional had an unfortunate influence.
