For the record: It’s an issue of MARRIAGE EQUALITY not “Gay Marriage”.
Many of the people who marry their same gender partners are BISEXUAL!
Edit: Just to add to the list there are also Trans*, Pansexual, Genderfluid, Genderqueer, and many more people who have a stake in marriage equality. And just as a friendly reminder marriage is not the end of this fight.
Umm … always remembering of course that quite a lot of Bisexual People are also Trans*, Genderfluid, Genderqueer or otherwise Gender Non-conforming. While absolutely sure that was just written in an attempt to be super-inclusive it can sometimes be read as accidentally “othering” all non-Cis and/or non Heteronormative/Homonormative bisexual people.
