I have quotes from the formspring archive. Relevant bits on Kanaya: "But then, homosexuality in a society where bisexuality is the norm is kind of a different thing. Rather than being a swapped preference, it is a more exacting preference. Somewhat like a fetish for a particular gender." and "Not that any of this changes how we view Kanaya. From a human perspective, she's an unmistakably gay character."
Well there you go then.
