Burt Lancaster was an absolute top man. Look him up!
I am a bit older than you I suspect, but I have a feeling he was sneered at by commentators during the 60s and 70s because commentators were appealing to a gallery who would have regarded a white man supporting Civil Rights in much the same way that NSC's Droopy would regard anything mildly pink, red or brown. Being an impressionable nipper, I would have been influenced by the sneering. Later I saw the error of my ways. And Local Hero was pure class.
By contrast, the right wing hypocrite cat among the pidgeons was John Wayne.
I read a Barry Norman anecdote about the Duke. He said that he was granted an interview during the time of the Vietnam war ,with the draft dodging far right great American patriot, who , during the interview said that America should nuke Russia. Norman, thinking it was a joke, laughed, Wayne had him physically thrown out of the hotel room.
