did I say otherwise?
This is incorrect. You are fundamentally and categorically wrong. Not a personal attack but a factual statement; there are differences in the inherent meanings different people attribute to different words. You are at the point now where this all comes down to how one interprets the words that interpret data, which of course depends on conclusions and interpretations, etc, etc. If you know another language then you know that ideas are expressed differently in other languages and seeing as language controls how we express ourselves you'll just have to accept that you're part of this clusterfuck, welcome to the club.
Sigh....Leigh, think of it this way:
Do people in the same family look alike?
Can traits and physical characteristics and tendencies be traced within a family tree?
Do a little projection on that and try to imagine there was a period of time in which human migration was much more restricted. It's that simple.
