Ten years ago, bisexual people found their relationships were treated differently in law based on the genders of themselves and their partners: today, after so much equality campaigning and the introduction of civil partnerships, that situation is exactly the same.
Bi people get into relationships with lesbians, gays, straight people, [Ed Note: and trans* people, genderqueer people, asexual people, people with no/different labels, etc., etc.] and other bis. Gay and lesbian people get into relationships with bis. We are your queer family. And LGB equality is only worthy of the name if we break down the barriers around civil partnerships as well as marriage: campaigning and lobbying for anything less puts the lie to a claim to be campaigning for equality for lesbians, gays and bisexuals.
