sighA species in a fantasy world, brought into being by an evil god, with a bloodline thinned to the point of having an option to be a player character, with the lore stigma of having ancestors of evil God spawn.
Forcing a real world judgment on a fantasy concept to create a connection to be far more alike than it is, seems more of a bigoted thought.
Taking that lore away seems a perilous thing, like burning the history of a place because you're the new conqueror. Rewriting a history steeped in Tolkien fantasy, of orcs being fell creations. Drow being beholden to Lolth, etc.
A iteration of that needs to remain. Amending it to including a couple more background concepts of usually-fell races is a better idea than burning away their lore to put something completely different in its place.
Right, look. Lore is mutable, changeable, and has no bearing on what I was even talking about. You asked how people could find stuff in the PHB harmful. Well, here it is.
Half-Orcs: Mixed blood children of humans and a "low and brutish race". A race who before this edition, likely raped the women who bore half-orc children. The race that is tribal, violent, savage, along with features such as sloping foreheads. If the children are not raised in the violent orcish tribes, they are in the slums.
Tieflings: Also mixed blood, also of an evil race, also living in "the roughest parts" of towns, where they are swindlers, crime lords and thieves.
Both these races are depicted with a dark purple skin tone.
Half-Elves: Mixed blood, but with a good race. Also, the picture is white. Also wearing gold, red, and white clothes. They, like the tieflings and half-orcs don't have a society of their own so they... grow up between both worlds, sometimes forming small communities and being diplomats between their societies.
Additionally, none of the other phb racial options mention poverty or slums or crime at all. The only people specifically called out as poor and potentially criminal are the darker-skinned children of humans and evil races.
And sure, orcs are evil, so of course the children of orcs and humans are discriminated against, given fewer opportunities, and forced to live with lesser means.... but doesn't that sound an awful lot like some real world problems people might have? Might someone who has these real-world problems see this depiction and wonder why, since it is an option for anyone to be a street urchin or criminal, why these two races specifically get called out as such?
