I wouldn't say I stress over them, I just prefer to research them and give some slightly more accurate depictions. Generally tends to annoy less people. As for geisha, the only real representations of geisha as prostitutes in history were hotsprings geisha (not real geisha, more like tourist attractions) and the 'geesha girls' of WW2 who told GIs they were geisha because they thought it was a good way of trying to call themselves 'entertainers'. The GIs, who didn't know what a geisha was to start with, thought geisha = prostitute. That's not to say geisha never engaged in more intimate practices, or even that money never crossed hands, but that's more of an individual basis. "Geisha" as a whole are talented singers, dancers, musicians, comedians, conversationalists, and walking images of traditional Japanese art.
