There's been some recent discussion as to why bisexuality tends to fly under the radar in fandom, particularly as it relates to slash fandom where characters with canonically heterosexual love interests/relationships/tendencies are frequently written as being closeted homosexuals rather than bisexuals.
My pet theory is that, in part, this has to do with how fandom labels fics with romantic/sexual pairings. As it stands, there are only two widely accepted labels for romantic/sexual pairing fics: Het and Slash, both of which tend to imply/reinforce monosexual portrayals/attitudes in fanfics. We'll get to my reasoning in a moment but first...
