Unamerican?
At least Dennis Hopper became a Conservative later in life.
Don’t get me wrong. The film is a work of genius and the motorcycles - especially Peter Fonda’s - are iconic.
Among the things you see in the film is hatred of Southern white men. They are depicted as gap-toothed, slack-jawed, intolerant and violent. Nowadays, the elitists treat all non-gay or metrosexual men this way. (Hence, the thread is about renaming John Wayne Airport.)
Regarding the Fonda’s iconic motorcycle (and American flag helmet), back in those days, the cultural left put American flags onto a lot of things. Today, we view this as patriotic. It has caught on. (Yes, somethings that the cultural left advance catch on.) But, at the time, it was considered by slow-changing conservatives to be irreverent. Ditto American flag athletic wear and bikinis.
As for me, I think - when a pretty girl is wearing an American flag bikini - I should salute.
