setissma wrote this thought-provoking write-up on why she thinks the Sam/Dean incestuous relationship ( fanon if not canon, though really, there's a very fine line there ) is pretty much inevitable. And this coming from someone who do NOT think that incest in fanfics ( I'm not talking about RL here ) is okay. Until she discovered Sam/Dean, that is.

Do give it a read, even if you're not into Wincest. The discussions in the comments are pretty interesting, too.

"When you have a good relationship with your siblings, sex doesn't come into play because sex wouldn't add anything to the relationship. It's on a different level." It was also that, for personal reasons, incest hit major "no" buttons for me. (I still won't read parent/child incest. Just... no.)

ETA: And slightly out of topic, quoting peripheralsight :

A wise friend of mine once said that the new trend of trying to defuse the homoerotic tension of the buddy genre by making the buddies brothers only leads the fangirls on to greater sins.

From here.
