Fandom Meta

So last night I was talking with paradise_city about incest fic. And well, it led me to a question, and I'd really like to hear what my flist has to say about it.

Fandom has a lot of different kinds of relationships portrayed, and a lot of them are outside of things that we've seen or thought we might enjoy (reading or in RL) before we came to fandom. Some of them are/were outside our moral code. Some things that we used to think we wrong, we may now think of as right, or vise versa. Some things we never thought we'd like, we now love or vise versa.

Are there things you've run across in fandom that have changed your personal moral code I mean mostly in regards to relationships, but you can include other aspects as well. Also, if you like something in fandom/fanfic, does that mean you'd accept it in RL? Or do you draw a line between fiction and reality?

I mean, there are a lot of people in fandom who read incest fic, if you came across an incestuous couple in RL, would you be ok with it? What about things other than incest? I know my first change way back in my early days of fandom was to finally see that an open relationship could work, if both partners wanted it. Or later, that threesomes, or moresomes could work. I grew up in a very traditional household, where mostly, it's expected for a girl to meet a guy, fall in love and get married, so seeing all of the other kinds of relationships out there really changed my view on these things, and moved some things off my moral codes list of "wrong".
