No, you seem to be very confused, as there is no f8cking such thing as a so called "Negr@id" Haplogroup.You're very confused,
but that is just a nice way of pointing out that you are FULL OF SHÍT.
No one is "claiming" anything except very confused individuals like you Afro-Centrist slack-wits.
No one is saying that Ethiopians are entirely Caucasian and what you don't seem to understand is that NOT ALL Ethiopians are part Negroïd.
Strictly speaking, the 'E-M78'Y-Hg is NOT a Negroïd Haplogroup,
and the same can be said for the 'L3'mtDNA Haplogroup.
Of course, no one is saying that all the subclades of 'E-M78'Y-Hg are Caucasian either, except for 'E-V13'Y-Hg.
What HAS been stated by anthropologists, is that the 'E-M78'Y-Hg is less distanced from Caucasian Haplogroups than it is from all Negroïd 'E'Y-Hg subclades.
L3 came from Sub Saharan Africa and EM78 emerged in the region of Northern Africa that would have had much Black presence as it is most likely to have originated in or near the Upper Egypt and northern Sudan region.
In any case, your argument stinks.
