Friendly reminder that Dean does NOT even have to be bisexual to date Cas, because:
Castiel literally isn’t male. It is canon that the angels in general are agender/nonbinary. I mean, obviously he’s not female either, but:
Dean is perfectly aware of the fact that angels are actually genderless/sexless celestial beings (“You have been with a woman before? Or an angel, at least?”) and yet he’s slept with the angel Anna (note: the angel that was supposed to replace Cas).
Even if Dean’s straight… and even if we take into consideration that Castiel’s vessel is male (which doesn’t really matter) or that he may actually identify as a male at this point or whatever: you do NOT have to be bisexual to fall in love with a person of the same gender. You can be a straight guy and still fall in love with another guy (or anyone that’s not a woman), because:
Love. Isn’t. About. Fucking. Yes, Castiel’s vessel is male, but it’s not like we fall in love with other people’s genitals, right? I’m terribly sorry to break it to some of you, but not everything is about dick, so like… How about we stop making everything about sex (in every sense of the word)? I’ve seen people accusing Destiel shippers of sexualizing their relationship (yes, it’s true that there are people who just desperately want them to fuck while completely ignoring the emotional aspects of their relationship, but what can we do about it), but really – if saying “Destiel would never work because Dean is straight” (meaning: “because Dean wouldn’t want to have sex with Cas”) isn’t sexualization, than I don’t know what it is. They don’t have to bang, since their relationship is about so much more than sexual tension. You don’t have to have sex for your relationship to be valid, so seriously, this is such an ignorant thing to say, guys. It’s the fact that these two support, protect, need, love and care about each other unconditionally that makes their relationship so beautiful. The fact that they would never give up on each other. That they can communicate without saying a single word. That Cas makes Dean a better person and vice versa. That they would literally die for each other. That they care and are unable to kill one another even when they’re brainwashed or corrupted. That they would shake up Heaven and Hell for each other (and Earth, and Purgatory, and all those alternative universes, too). The way they gaze at each other. Their chemistry, loyalty, tenderness, trust, the slow burn and this damn “profound bond” – so unique, I’ve honestly never seen any canon couple share this kind of connection before. I could go on for centuries, but you get the point.
What I’m trying to say is that their relationship doesn’t have to be sexual. It’s romantic - and that’s what is special about it. It isn’t about two dudes looking hot while making out - which is actually what a lot of other show and movie makers think a queer romance mainly is, no shade. That’s why Destiel going canon would be an amazing revolution in terms of the portrayal of LBGTQA+ relationships. And I honestly don’t understand what’s so wrong with it or why anyone would be against it.
I’m sorry, that’s just the way I see it, please don’t start drama. The “Destiel can’t happen because Dean is straight” argument is just so invalid to me.
