As I believe that Buffy is straight,
I mean no offense. Really, I don't. And I hate to keep having to bring this up. But I need to point out again:
If we're going to be using the labels here, then we need to use them correctly. That's the pitfall of using labels: sometimes the one you
want to use is not the correct one.
These words have specific meanings. "Straight" in this context means "someone who is exclusively sexually attracted to members of the opposite gender." That excludes, by definition, "someone who enjoys sex with members of the same gender."
Someone who enjoys sex with members of both genders, as Buffy has been shown to do, is "bisexual." That's the label that applies here, if one must.
Just as "gay" would be an inaccurate descriptor, so is "straight."
This is not a matter of opinion, but of correct or incorrect usage of the terminology, as applied to what's been shown to us right there on the page.
The notion that this was some kind of slumber-party experiment or drunken mistake on Straight Buffy's part is directly contradicted by every aspect of the incident as recorded in the comics. It was a deliberate, enjoyable interaction with emotional resonance for both women. It's not an aberration in Buffy's sexual history. It is an addition to it.
Buffy has not seen fit to apply any of these sexual labels to herself. People have only been doing so on her behalf, both inside and outside the comic. And as we continue to see, this only leads to conflict.
And I think anyone can see that in this preview, Kennedy is the Queen of Not Knowing What She's Talking About. What possible basis does she have to comment so extensively here? Did she listen in on any of the conversations between Buffy and Satsu? No. She's just wigging because for the first time, she has to picture the Mighty Buffy as a potential rival for Willow. And she's trying to reassure herself.
