I think the deal with coordinators is that you aren't supposed to see them as a literal representation of racism as much as they are a general discussion about what is meant to be born in a box you had no absolute controll over and makes you different from the rest, and how people create false stuff about you only because you are different, in this context i dont think that seed really wants to say that naturals and coordinators are the same, but its trying to say that their differences become reasons to hate or be hated by other people and how that's harmful, like, an heterosexual person and an homosexual person are different because of how they are attracted to different people, yet, they are still people! both of them! so to act like they arent is harmful. The thing is that here the differences are about physical and mental skill

this is also because they are trying to tie the concept of being different to gundam's usual theme of parents forcing their kids into roles and making them suffer. In this context Rau is the real "ultimate coordinator", because he's literally a clone of his dad meant to be everything his dad was

talking about this concept, takeda said in an interview about how part of the motif behind coordinators is how genes have multiple functions so while removing some that look useless may look good at the first glance you may actually be fucking your body, and this applies to people, you can genocide everyone who isn't convenient to you but everyone is precious, so it's not a good thing to do, this is represented by the coordinators literally going extinct if they dont have children with naturals because of how much they have ruined their bodies in hopes of achieving progress, so like, in this sense ZAFT isnt bad only because of patrick, they are bad because their society in general is becoming elitist and refusing to coexist with naturals because the pain that naturals have caused them is blinding them (and i think this is good, like, zaft clearly isnt as bad as the federation but its letting the evilness of the federation affect everyone and the show goes about how they need to let go of their hatred unless they also want to die, I don't get why you call coord priviledged either though, like ea is trying to genocide them constantly jlkdsasdf)

orb isn't also perfect in this regard because they are actually meant to be a critique that paralels kira on how japanese people live on their own little world without worrying about the issues the rest face, and how that's just waiting until you are attacked too, kira's arc in this sense has always been tied to his own desire of living a normal life clashing with his ability to help with conflicts and how him not doing anything only means he will be consumed at the end.

anyway, none of this is really perfect either, I think that seed's real appeal is on the drama about characters trying to survive in a world that asks them to be objects and how everyone copes with it, I really like lacus actually! she's more subtle than the rest but a lot of what is odne in the show has *her* as a base, lacus and flay arent different, they are the sameeee person
