I've already posted a wee bit of film "history". :-)
Yes, the pre-code movies were filled with fun sex or dour social messages. The head of Film Forum in Manhattan is an expert on pre-code and runs them all the time. It’s how I discovered the protean Lee Tracy. I like pre-code very much and couldn’t care less with what some dumb broad in North Carolina has to say about “sex harassment” in the 1920s. I prefer to take my Louise Brooks and Thelma Todd and Stanwyck and my beloved Clara Bow neat.
Fatty was innocent. Miss Rappe had a habit of going wild and undressing at parties and later claiming assault. He was railroaded because he was fat-shamed, if you can believe it!
