What are people's opinions on swearing in fantasy? I'd like to simply use conventional swear words like shit, fuck, dick, cunt, etc. and maybe just remove some cultural specific ones like, 'Jesus, Christ, or Jesus Christ' etc. The story is somewhat dark and a little gritty, and is probably aimed at more mature audiences but there are also sections that are quite light, fun and even comedic. Are there any strong opinions out there about this?
