Too many people on this site are pro hive. It is a BAD THING. People seem to think Carol is meant to be an example of a racist white lady forcing American individualism onto another culture, this is NOT THE CASE and it is a gross misreading of the text. The Hive is a painfully clear allegory for forced assimilation. They practically state it in the show, the characters might as well be looking at the audience and saying "WE ARE TALKING ABOUT ASSIMILATION AND CULTURAL GENOCIDE".
The survivors who are cool with the hive and refusing to accept that their loved ones do not exist anymore and are (for the time being) essentially dead are the people who assimilate willingly, then refuse to admit that they have done so or argue how it was a good thing.
Manousos is a Colombian man who has watched his home and culture be eradicated through assimilation, with his mother being stripped of her true personality and behaving in a sterotypical 'loving gentle mother' way that contradicts her true personality, while he actively fights against the colonization and destruction of these things. Looking at it allegorically, him accepting the hive would be like him changing his name to something like Mark and getting embarrassed and ashamed whenever anything related to his old culture is brought up.
Carol is a lesbian woman who believed she had to hide her homosexuality from her readers, else risk no one being willing to engage with her media. She literally changed the gender of the main love interest of her novels because she believed it to be the 'safe option'. She is also literally a Conversion Therapy survivor. Carol ALREADY had to actively fight to remain true to herself as a member of a marginalized group. Joining the hive would completely erase her identity as a lesbian. Looking at it allegorically, it would be the version where the conversion therapy traumatized her so badly that she ended up marrying a man and pretending to be straight for the rest of her life.
In the hive there are no lesbian's, there are no columbians, there are no real people. When Koumba says that skin colour does not matter, that is literal and all encompassing. It doesn't just not matter in the fact that there is no oppression, it doesn't matter in the sense that all culture has been eradicated. It does not exist anymore. It is essentially a full and total cultural genocide of the entire planet. When The Hive tries to comfort Carol by telling her that they are very accepting, she is really saying that when Carol is a part of Them there will be nothing to accept, because they will all be the same anyway.
The Hive is the social pressure for trans people to detransition to avoid being assaulted, it is little girls being forced to play with dolls if they want cars, it is little boys being forced to play with cars when they want dolls, it is being made fun of for you accent until you learn to erase it, it is autistic people being mocked for stimming.
The Hive is colonialism, it is cultural genocide, and it is conversion therapy.
