We see Sam sleep with a waitress, flirt with a gas station cashier, flirt with/have a crush on Eileen, have a crush on a wrestling announcer, now this…
We see Dean get a hickey of unknown origin (while walking funny afterward), get rejected for having a “dad body”, have a crush on a wrestler, and freak out about Cas.
Sam winks at female bartender, Dean winks at male bartender, it’s all good, it’s all good.
There are people in this fandom that keep and keep spreading misinformation that has no basis in reality which a lot of people seem to take for the truth just because it has been repeated often enough.
The series creator Eric Kripke has never called Dean Winchester straight.In a round table interview in Comic Con in 2013, in just one of many, he spoke of his thematic of unstated homoerotic subtext in his work, paralleling the brothers Sam and Dean to the characters Sebastian and Miles from his new show Revolution, which was the topic of the interview, and he called Sebastian and Miles straight guys. He did not call Dean Winchester a straight guy. At no point did he call Dean Winchester a straight guy. He has never called Dean Winchester a straight guy in any recorded interview in the last eleven years. Eric Kripke has, however, confessed on his own twitter account that he used Hellblazer, Good Omens, American Gods, and Sandman as his inspiration for The Pilot episode. These influences have something in common.
It also falsely claimed that all the writers either think Dean Winchester is straight (which is naturally unverifiable but extremely unlikely), or that all the writers have in fact said that Dean Winchester is straight.
That is all we know about the opinions of the writers even tangentially related to Dean Winchester’s sexuality. And this is only a small handful of writers. Not one of the writers currently writing for the show has ever called Dean Winchester straight, not once, not anywhere that can be verified.
In the interest of not falsely presenting the evidence, I will also add that the director Guy Norman Bee has stated on twitter that Destiel is not the story. He was, however, not commenting on Dean Winchester’s sexuality.
The only person that has claimed that Dean Winchester is not bisexual is Chad Kennedy, the director of current programming at Warner Brothers. His opinions, however, do not reflect those of the CW or the creators of Supernatural, as his twitter disclaimer was subsequently changed to state.
