I wouldn’t say Blazing Saddles itself was overtly racist, but it did depict the overt racism of the day. It is even coded in the movie that racism is bad. The villains are all racist with some forms of self awareness of the situation. The redemption of all white hero characters require that they try to stop being racist.

I felt like Django Unchained did the same thing, but as a straight up action movie. All the heroes believe in equality while dealing with an unequal system; all the villains defend the institution of slavery.

A lot of people focused on the movie saying the N-word without thinking of who said it in the movie and what it says about them.
