While this is commendable, it's hardly universal.
Edit: Eg there's a homosexual rape scene in Pulp Fiction that's played for laughs.
True, but it is much easier to joke about murder and torture around the game table than rape.
I mean, how many times have you been "killed"? There have been many a thread detailing, "what's your best/funniest death" and similarly, many a people will joke about the after-effects of torture ("hey Stumpy/one-eye" etc)
Have you EVER seen a post detailing, "how my character got raped?". I'm with ProfessorCirno on this one....
