Wrong. All people are human because elves and dwarves do not actually exist. The whole "all people are equal" only works because only humans are people.
If elves and dwarfs would exist, as we pretend them to be in D&D, they would be different to humans, again how we pretend them to be in D&D.
That's your assertion and one that seems entirely based on ignorance. Sentient human-like beings in fiction are very clearly stand-ins for humans with the whole "not technically a human" being used only to explain away having super powers. The character Wolverine from X-Men is technically "not a human" by the definitions of his own world and has a number of features that any normal human would not have anyway. So you are arguing that he, and others like him, should be inherently treated inhumanely and no understanding of human psychology should be applied to him? Then you could have a character like Superman who is even more so definitely not human, despite appearing human in all manners-- you would argue that human rights should not extend to him? He is not a person?
I suppose Commander Spock from Star Trek is also not to be considered "a person"? Or is he only half a person? How about Lt. Commander Data? Just property, just an object I suppose.
In Sci-fi and fantasy, any time you want to have a group of people who either have abilities beyond what we do or who are visually distinct, they are just called something else. But everything about them is still understood to be functionally human except in areas that are explicitly stated to be different. Beyond that, you are always to understand them to be just as much a person as any human, not to be seen as lesser or to imply that they aren't motivated like a human. It is just a matter of expanding the concept of personhood beyond our one fairly boring animal species.
I don’t think so. You missed out the word human in your sentence. Humans are not predisposed to be stronger, smarter, more charismatic or wiser than other human ethnicities.
There is nothing colonial or pseudoscientific about dwarves being predisposed to be tougher than Elves.
Which might be, at least in part, because the concept of ethnicity ends up being based primarily on some fairly incidental physical features. Also, because the most recent common ancestor of all existing humanity was only about 200,000 years ago at most and possibly as recent as only 50,000 years ago. There used to be a greater diversity of humanity that had dramatically different physical and mental characteristics, but they aren't around any longer.
But they were still humans of a kind. It does seem to raise the question in the terms of many of the D&D worlds whether it is at all realistic to have tons of human/near-human species all occupying the same general area for thousands of years without driving one another to extinction or interbreeding to the point that one couldn't really clearly discern one from another. And it isn't even like they are solely occupying different regions of the world and never crossing paths, but they are kind of inexplicably mixed together like a big salad in most worlds.
So whatever the heightened drama is for these worlds-- their reality is still far less harsh and brutal than actual reality was. These people are demonstrably more tolerant of one another's existence overall regardless of what we see in any given story.
