The secular word Semitic in pseudo-scientific reference refers to the Afroasiatic (Hamitic) languages North Eastern branch associated with Human Y-Chromosomal Haplogroup E1b1b1c. However it was originally a religious term used to refer to culture and heritage of the people who claim some kind of heritage from Shem the son of Noah. Confusingly it is still used in both senses meaning that two people could be using the same term while talking about two completely different things i.e. either things from Ham or things from Shem.
It is therefore very essential to be careful in discerning whether the term is being used to refer to people in a religious sense or in a non-religious sense, e.g. in reference to the African Haplogroups and dialects associated with North East Afroasiatic languages in which case Hamitic would be a better term to use rather than Semitic.
If one insists on using the term Semitic to refer to a branch of heritage from Shem then the Hebrew language would have to be re-classified as a North-East Hamitic language, and similarly Y-Chromosomal Haplogroup E1b1b1c would need to be re-classified as the North-East Hamitic Haplogroup although the term Hebrew itself would indicate a culture and people with siginificant Semitic (in the religious sense of the word) heritage.
An example of this confusion can be seen in the ubiquitous ignorance of describing languages of Canaan first as Canaanite (when they are actually closer to Cushitic) and then as Semitic languages when both Cush and Canaan were descendants of Ham. It is worthwhile noting that the genuine Canaanite Haplogroup is Y-NDA Haplogroup D however, which is associated with Sinitic culture and not with the North East Afroasiatic languages nor Haplogroup E1b1b1c which displaced the Canaanites to the East.
