What exactly is a demihuman? Are dwarves and elves demihumans? What about dragonborn and tieflings? Are demihumans still a thing 
?
Thought I'd fork this off of the other thread.
Here's something that gives an idea of how I use 'demihumans' in my 3.5 homebrew.
Playing a demihuman cleric
One aspect of religion in Knights of Everest is distinct: Demihumans are very private about their religious practices. Except for humans, each race’s religious beliefs and practices are mostly hidden from outsiders. Very little is known about a particular race’s religion by outsiders.
For instance, a dwarven cleric will almost never reveal to a non-dwarf that he is a servant of the Soul Forger. He would have to have been a longtime friend of the non-dwarf, and there would need to be some pressing reason for him to make this admission. A dwarven cleric would likewise only use healing magic on a non-dwarf if the other were a close friend and/or if matters were extremely dire.
This unique approach to religion means it can be challenging to play a demihuman cleric. The intention however, is to provide roleplaying opportunities, not to create hindrances. There are no hard and fast rules for how the secret should be kept, or for how and when it should be revealed. In our games, the reveal was a campaign event.

There are no secrets between the adventurers and healing magic is used freely and openly. If this is the case, then the whole party should be in on the secret, not just certain individuals.
Raising the Dead
The nature of religion in Alphere has the following effect: If a character dies, she cannot be raised by a cleric of a different race (unless a miracle or wish spell is expended, symbolizing intervention by that race’s deity). Human clerics are able to raise a character of any race.
I regard demihumans as Halflings, Elves, Dwarves, Gnomes, Half elves and Half Orcs. Aasimar maybe tieflings not so much as they are a bit to monstrous in appearence same with half Dragons despite being half human. Kender may also count along with the Mul. All the PC races in the 1E PHB count as demihumans basically.
Half humans or humans with "monster" blood such as Athasian Half GIants, Tieflings, Half Dragons do not count.

If I were to use the term "demi-human" in one of my campaign settings, it would be as slur that bigoted humans call others who aren't human.
"Half-human" maybe. "Demihuman" is just a less generic, more D&D way of saying 'not human'. Or at least that's how I use it .
Another term I use is 'dual-heritage', in reference to races like half-elves, half-orcs, and muls. This is my way of glossing over the gory details of their backrounds. Players decide for themselves if they wanna go into more detail.
Has anyone heard this term used before? I can't remember where I picked it up (and I'm sure I did, somewhere).
Demihuman as term has more or less been replaced by humanoid.
