Under modern values and education; superficial, or otherwise uncontrollable constant characteristics of individuals simply don’t matter. Rather, the “content of their character” and their values do. What they represent as pertaining to human qualities, goals and ambitions… but also vices, mistakes and imperfections… All of those alone are the obvious makings of a compelling, repulsive, or complicated characters.
Abandoning putting in the effort into writing a compelling story due to trying to achieve a mystifying “New Man” notion (cherry-picking or even undermining human nature) is just futile, and morally suspicious. Misrepresenting reality, by treating minds and ideas as group representatives and inserting characters of certain groups over others out of some desire or edict for ‘justice’ (vengeance) doesn’t achieve anything but further division - instinctual tribalism, which is regressive.
If somebody cares about what the superficial details are, that’s the first indication of the problem. Instead of bickering over which group needs more characters, it’s more productive to just naturally write a variety of individual characters with human qualities – as is the way fantasy has always worked and succeeded.
Escapist entertainment is individual and universal, not tribalistic and collectivistic – because that’s how human nature also works (we share a genetic basis, but are obviously NOT a hivemind, unless we CHOOSE to be…)
It’s crucial to keep the latter set of regressive ideas (the mystifying, de-humanizing morass of post-modernism) OUT of areas which are crucial to human flourishing, in accordance with reality. Keep it human, pro-human, for human beings. We are not Ants, nor robots, aliens or deities.
If somebody wants to present their own innovative ideas, they should create a new story and independent characters through which to deliver them. The refusal, or inability to do that, in-turn, reflects on THEIR psyche as an artist (or consumer, for that matter). Under the test of reality… Well, the audience can speak for itself, and the outcome of going by anti-modern trends such as group identity proves its own de-constructiveness every day.
