I'd agree, and its become more of one with a push for generalization without definition.It's interesting to me that occasionally this discussion refers back to the Tolkien-derived races, when even in his own works we can see that elves, dwarves, and orcs all have, or are implied to have, different cultures. This is very much a D&D problem.
If Wizards would properly support its other settings, it wouldnt be such an issue, as people would be less likely to assume that the core books are the Gold Standard and No Deviation Allowed.
(He says, despite the CLEAR language saying deviation is both permitted, and recommended to the DM lol.)
