Yeah yeah yeah. The point is context, and without the context there is no point. The movies were made when they were made, and the context led to them being made as they were.
Harold Ramis clearly said about ten years ago that he would never film the St. Louis scene if he had made the movie today.
Look at Eddie Murphy Delirious and Raw and have the same discussion about homophobia.
Movies from back then don’t need to be FIXED. They are what they are. Every movie or TV episode ever made is a time capsule for its era.
