Okay, this is starting to turn into the "one drop of black blood equal black" kind of hard line - in other words, nonsense. Definitions aren't always "hard line". At some point, fog is just mist. I'm "white" but I'm 1/16 Apache - does that make me Apache? That's what I'm saying - that though we can make a general statement about any concept, there are likely to always be outliers and hybrids that don't quite fit in any simplistic labeling system
