Not at all, this was the part that I actually agreed with, I just pointed out that if all you are giving are "quirks", you will just be having humans in funny hats, and that it's very different from what I see as the right way, to give much more than that and in particular unique powers and abilities to the races and derive the race's usual cultures from this, as has been done in probably every good fantasy book and movie of the genre ever since it was created. Because it makes the worlds really fantasy worlds, rich and vibrant, with differences and surprises, not a bland mix of quirks that everyone ignores.
