I have mixed feelings about this, because the implication that a relationship between a bisexual person and a straight person is *identical* to that between two straight people is off base.
Do I have privilege because I married a man? Yes. But I also raised my risk of domestic violence substantially, reduced the support I got from the LGBT community ("Presenting as straight," anyone), and our relationship is *not the same*.
Some of that is positive. I and my husband have somewhat similar taste in women and get to bond over just how ridiculously hot Morena Baccharin is.
But not all.
To call our relationship a "straight relationship" is to deny nuance. Furthermore, it plays into another issue, which is the black and white duality between gay and straight then then sorts bisexual people by the gender of their current partners.
The author says she doesn't care if we're bisexual, but she still wants to erase the difference in our relationships and it is very close to "straight passing" *shudder*.
No, a haircut doesn't make us queer. But a husband doesn't make me not queer...and it doesn't make my relationship "straight" and no different from the relationships of my straight friends.
