Yes.
In the Jet Li and Jackie Chan films that are set in a somewhat mythical, or at least romanticised, 19th or early 20th century China, when they want to depict colonists they just cast white people!
And? The point being made about Orcs and their cousins is that when JRRT wanted to depict "the monstrous", the most monstrous things he could reach for drew on stereotyped tropes of "Eastern" hordes.
This is a highly contentious claim in the philosophy of value. Prominent philosophers who disagree with it include Bertrand Russell and Jean Paul Sartre. So it's not exactly a stable platform from which to launch an argument.
Again you make the assumption, wrongly, because you do not know my lived experience or educational background. I have written a Master's thesis with Harvard referencing so understand the academic peer review process and research methods, including statistical analysis.
Hence quoting to correct sets up failure.
Good and evil are shorthand for frames of reference used across human traditions and cultures. You could consider it the most rudimentary set theory. Basically, evolutionary survival encoded into symbology.
We may ask why are diseases considered bad when they are useful natural parts of the ecosystem that serve a purpose?
From the human perspective, due to the negative effect of disease on human populations, disease is considered bad and this is seen globally across cultures and populations. Ancient gods linked to pestilence and plague are considered evil.
One of the challenges of the modern interconnected world is the loss of a common frame of reference, hence so many arguments online.
For example, if there is objective bad-wrong-fun, then all wil agree. Yet, all do not, so when one group tries to state it unequivocally, you get resistance.
We can look into some mythic traditions of the dead. In African culture, a connection to ancestors makes the spirits of the dead more like guardian angels of Western myths. Yet in Western based RPGs, ghosts are not do considered. However, fear of The Other is also common in African tribal folklore, for valid reason. The unknown stranger could be a plague bearer. Our current pandemic showcased how bringing the unknown home brought disease home.
Obviously, with modern science, we can re-evaluate ancient customs for the better. But this too is subjective. The early shelter at home orders for the pandemic were good for society but bad for individual households with infected members. This brings unto play that Ursula Le Guinn trope from The Left Hand of Darkness about socially approved sacrifice. Then you may ask why two tropes were linked negatively. Left hand and darkness Modern science tells us both left and right hands are equal. Ancient tropes are not perfect, the fear of darkness comes from ancient times when light was scarce at night and humans lacked night vision. Moving at night was risky, many predators hunted at night. It then became shorthand for evil.
