I’m just saying:

“The movies try and play up things that will be appealing to the audience. On Television,Superman stood for Truth, Justice and the American Way. While that was being said, an American flag was in the background.In the second Superman movie, at the end,he places the American flag on top of the White House. Raimi, sees Spidey as the New Superman.Also, flag poles are a very common object in Spider-Man comics that Spidey swings from,grabs to save himself,webs criminals to(along with light poles). So the use of the American flag poles is a very common device within the history of Spider-Man.

Spidey rules from sea to shining sea”

seems pretty patriotic to me
