Robert Heinlein wrote incest in at least one of his novels (brother/sister). As others have said, fandom isn't the first place these ... uncomfortable ... themes have been used. And it won't be the last.
As far as "responsible" writing goes, I'm not sure it's up to the writer to warn or research or include the impact on victims. I know Heinlein's book didn't have an incest warning on the back cover.
In a way, this is just another version of the "condoms, yes or no, are we being responsible?" discussion. All the choices we make in writing our stories have the potential for both positive or negative impact on a reader, and there comes a point where it's up to the reader to be responsible for their own choices.
