I am no longer young, which is to say I was there at the time -- I saw the original run of Blazing Saddles in the theaters, and can tell you from experience that it gives an accurate account (within the construct of a fictional 1800s comedy Western) of the racial zeitgeist of the time.

In many ways (although not all), today's racism, prejudice, and discord are far worse than they were in the '70s. Blacks were economically and socially far better off than they had been -- racism was fading as blacks, whites, asians, and everyone else were simply getting used to the idea that PEOPLE ARE PEOPLE -- and everyone was better off than we are now, with the constant pushing for race-hatred by the cabal.

Q pushes for UNITY, and few things are more important. We are all brothers and sisters, and, in a strange, rude, comedic way, Blazing Saddles showcases that.
