Now, in a recent interview, Wonder Woman writer Greg Rucka has definitively stated that yes, Wonder Woman is "queer" - though he also admits the answer isn't exactly black and white.
Defined in the interview as "involving, although not necessarily exclusively, romantic and/or sexual interest toward persons of the same gender," Rucka told Comicosity definitively that Wonder Woman is queer - however, the people of Themiscyra don't define their sexuality with the heternormative terms of "man's world."
"Yes. I think it’s more complicated though," explained Rucka. "This is inherently the problem with Diana: we’ve had a long history of people - for a variety of reasons, including sometimes pure titillation, which I think is the worst reason - say, 'Ooo. Look. It’s the Amazons. They’re gay!'"
"And when you start to think about giving the concept of Themyscira its due, the answer is, 'How can they not all be in same sex relationships?' Right? It makes no logical sense otherwise," he continued. "But an Amazon doesn’t look at another Amazon and say, 'You’re gay.' They don’t. The concept doesn’t exist. Now, are we saying Diana has been in love and had relationships with other women? As [artist] Nicola [Scott] and I approach it, the answer is obviously yes."
Rucka goes on to explain that it's important that Diana's first romantic relationship not be with Steve Trevor, otherwise her drive to leave Themyscira would be motivated by love rather than sacrifice, which he explains "takes away her heroism."
"When we talk about agency of characters in 2016, Diana deciding to leave her home forever - which is what she believes she’s doing - if she does that because she’s fallen for a guy, I believe that diminishes her heroism. She doesn’t leave because of Steve. She leaves because she wants to see the world and somebody must go and do this thing. And she has resolved it must be her to make this sacrifice."
