They do not take the financial success of patriotic movies as lessons on the culture.
At best, they have figured out how to use decent, patriotic movies as "cash cows" for perverted ones (i.e. make one "Private Ryan, earn enough for ten "Priests").
Hmmm...Hollywood has in fact changed between 1945 and 2002. But please don't misunderstand...I don't think we'll see a patriotic Hollywood anytime soon! It may well be when my grandchildren (who aren't born yet!) grow up before the pendulum swings back to the right!
