"Cas is in love with humanity" - but what it really means is "Cas is in love with Dean." --- One could say I am "in love with queer" but what it really means is "I am in love with my girlfriend." --- It just sounds like Cas's awkward family trying to find the most awkward way to explain that Cas is now part of the 'humanity+ community' without actually acknowledging his human boyfriend or his own 'human-ness.'
I’ll be honest I stumbled a bit with this ask. But I think I get it. the homophobic family trying to create a disconnect between the actual person, and the idea as a whole. Its like when people describe their queer family member as having a “lifestyle choice” rather than actually accepting them as a queer person who was born queer.
This fits in with something I was discussing with @godshipsit not too long ago. We talked about how the way the angels treat Cas and his “love for humanity/Dean” is a giant metaphor for homophobia and the struggle that LGBTQ+ people have with coming out to their own homophobic families.
Check out this post for a nice summary of this metaphor with some very obvious examples.
This has been in place since the beginning of Cas’s story arc though, with his “considering disobedience” and referring to Anna for advice (Anna the angel who choose to fall, rejected her family for “human things” such as sex), being his decision to come out of the closet and break away from the controlling family he belonged to.
Other moments such as this great line: “You’re the famous spanner in the works. Honestly, I think you came off the line with a crack in your chassis. You have never done what you were told. Not completely.” can easily be seen as a homophobic person talking about how they always thought their queer family member was ‘different’. It has only become more prominent since Cas and the angels truly parted ways in season 10, with the angels forcing Cas to choose between them and Dean each time, threatening violence against him when he chose Dean, and going so far as to try to “cure” him.
We have often mused about how exactly the other angels see Cas and Dean’s relationship. With it being pretty clear in the subtext that they feel there is a sexual relationship there (11x02 demonstrated this quite clearly as did 12x10). So progressing on from this thought to seeing the metaphor of a homophobic family trying to “cure” the queer relative is suddenly really obvious and it makes Cas’s entire relationship with his angelic siblings all the more sinister… especially now that he has gone back to heaven to face them in 12x15.
It is even clearer when you look at how the other angels treat Dean in the later seasons. They are always threatening him or using him as a means to manipulate Cas. It is never Sam that they threaten to kill, because the angels don’t see Sam as the same kind of threat as they see Dean. In their eyes, Dean is the human whose “touch corrupts” and who is responsibly for Castiel going down this path to disgrace. Naomi, Metatron, Ishim, they all went after Dean in order to “cure” Cas in their own way. Thinking that by getting Dean out of the picture, Cas would go back to the way he was before he “fell”.
Basically, you barely have to scratch the surface to find this metaphor, but once you see it, its impossible to un-see. Cas is the queer man, trying to find happiness with his lover, but who is constantly threatened by his homophobic and powerful family, who will seemingly stop at nothing to get him back in the closet… going so far as to torture him, brainwash him (conversion therapy much?), kill his lover and even try genital mutilation.
Its pretty fucking grim. But its right there in the subtext.
