The 100 does so much to positively represent diversity. This show depicts a world in which multiple major characters are gay or bi, and that has absolutely zero impact on how they are treated in their society. It’s a world in which women are equally likely to be leaders of their people, and no one ever acts like they feel silly following a woman’s orders or treats women like they are weaker or lesser in any way. Being gay or bi, being female, being a person of color — none of these things is treated as even a topic of conversation. The world of The 100 is brutal in many ways, but it is almost utopian in its portrayal of a society which treats gender and sexuality as genuinely unremarkable, just natural human traits that are not to be looked down on.
I’ve been disappointed that the fandom has been so ready to dismiss all the positive efforts of the show’s creators and ascribe negative intent where it should have been clear to everyone that none was likely. The goodwill built up over years of progressive storytelling should have counted for more than that.
