For those of you who don't know, during that RP i made a series of "Hal having a trip-out" scenes where one of the scenes in question was "Green Lantern: The 1950's Serial" Where all of the characters in my story were reimagined as 1950's versions of themselves. And being that the 1950's were not exactly a time when African-American representation was very kind to that community, i portrayed John Stewart during this scene as most African-American were portrayed, albeit tuned down. No N words or anything (I had the sense to not do that) but i'd say
Along these lines I thought it would be a funny little "Haha, 50's people were racist" that we could all have a laugh at and move on from. And to be fair, the only initial response i got from that was a thumbs up from someone. However, a few posts later some people took great offense to this portrayal.
Now, i am not saying that they shouldn't have taken offense. All things considered, it was a really bad place and a really bad time to make that joke and i do acknowledge that i DEFINITELY shouldn't have done it there and the DM's made the right decision to kick me from the game.
