Last thing, you mention how these things have always existed and no one has had a problem with them until now... but that's not exactly true. There's always been problems with this type of representation by people who actually have a problem with this kind of representation. That actually does exist. It was a smaller, more isolated problem easily waved away as just bigots being bigots, but again it just adds to the baggage of this current "woke culture" argument.
OK, i would like to elaborate on this.
Yes, during the various periods of the history of mankind, we had fluctuating levels of acceptance of “diversity”, due to religions, political extremisms and other factors.
What I’m trying to say is that we all come from very similar roots, and those roots were very inclusive.
I’m talking about the period of myths, legends and ancient poems, with the birth of some of the most basic tropes of literature, as the Hero’s journey I’m talking about ancient Greece and Homer, here. The most iconic hero of the greek classic literature was Achilles, and his relationship with Patroclus was more than just a “manly friendship”, as shown when Achilles goes MAD after the death of Patroclus (which, BTW, it’s a great example of “show, don’t tell”).
Staying on Greece, we have also Sappho, one of the greatest female poets of all times, which was lesbian. The term “sapphic love” comes from her. And her poems about her lover are studied and appreciated also today.
If we go to North Europe, we can pick the northern mythology. The Gods were basically a representation of the human nature, with our same vices. It’s not a case that there were so many treasons and sex outside marriage between the Gods. And one of the most iconic god is Loki… a guy that was a shapechanger, who was used to have sex with men, women and even beasts (look at the story of Sleipnir’s birth…). Talks a lot about sexual identity.
But it’s really a thing that you can see all across the world’s cultures, and is not related only to the sexual sphere.
In the native north American mythology, there are stories where there is a male god which is powerful but guillible, and the positive protagonist of the myth is a smart mortal woman that fools the god. A similar approach can be found in african myths (alongside with positive male figures... actions were important, not the gender)
The same can be said for Inuit culture. I'm not an expert, but in the only legend i know the positive figure was a woman and the negative one was a male god (which, if i recall correctly, was basically a stalker).
And of course China, with Mulan.
My convinction is that yes, there are minorities of people that are against inclusiveness because they are fundamentally racists, but all in all we came from that ancient cultural base. We accept diversity in stories as long as you stay true to the classical tropes.
The original Mulan is appreciated because there is a Hero's journey... that is the thing, and it happens the protagonist is a girl.
The recent live action remake was rejected not because "OMG, strong woman!"... it was rejected because it failed miserably in presenting a good story and a satisfying journey.
THe same goes for the new SW trilogy, or Capitan Marvel.
Give us good "woke" stories, and the bigots will be minority again.
