So, I GMed a short Call of Cthulhu scenario yesterday after a long hiatus from RPGs (work sucks). It was just great ... I have an awesome group and Roll20 is a great place to play. But as I GMed, I realized I was starting to get uncomfortable simulating the racism, sexism, and homophobia prevalent in the 1920s. The setting was 1925 San Francisco and many of the servants and lower class NPCs were Chinese-Amercian. The gangsters were first generation European immigrants ... I researched organized crime at that time and it really was run by immigrants in this one instance, in this one place. Some of the NPCs said awful things ... and they used my mouth to say it! Worse yet, I just met my players and they have no idea who I really am ... worried me that that I would take the rap for my NPCs awful activities. Now, I could just leave this material out but the 6th edition core rulebook from Chaosium (on page 26) makes a very good argument for leaving this material in! Simulating racism is "in the rules". But the rules for C of C were written over 30 years ago (WOW) ... are they still right? How do other GMs handle these subjects in Call of Cthulhu and other systems? Cheers!
