No, you have not.
At no stage have you provided evidence that Andamanese and Pakistanis are closely related member sof the same race as you claimed.
I think people might just remembered if you had done that. Proving that short black people and tall white people are closely related. 
No, Chen isn’t a liar at all. He is able to provide evidence for everything that he says, even when those things are mutually contradictory.
Apparently he has provided evidence for the claim that in NZ Caucasian refers to those whose ancestry is from Europe.
And he has also provided evidence that **in NZ Caucasian refers to people of entirely Asian ancestry, such as Lebanese.

Nope he’s not a liar at all, having provided evidence that Caucasian refers to those of European ancestry and refers to those with exclusively Asian ancestry.
Quite clearly Chen is God, since he can prove that two mutually contradictory statements are simultaneously true.
Please keep going Chen. This is some of the funniest stuff I have ever seen on these boards.
