Semitism is a set of science-backed cultural practices that dates back to ancient Sumerian civilization.
It constitutes three basic practices, and these are the three instructions of the Oral Torah that Abraham instructed his descendants to pass down from one generation to another by word of mouth.
These practices are :
(1) Reproductive Fidelity:
It is a cultural practice of which a female is taught from early childhood that when she grows up, she must keep to only one man for all sexual activities from the age of virginity until she decides not to bear offspring any longer.
This practice was inherited by the Hebrew women, most particularly the women of the Levitical tribe, and this teaching was incorporated into the original Oral Torah handed down to the Hebrews from Abraham, who originated from Sumer.
(2) Kashrut: certain meats are forbidden. [Here] is why.
(3) Reproductive Segregation Protocol/Anti-Genetic-Diversity Agenda: Jews are commanded not to intermarry with non-Jews, and to do everything possible to preserve their gene pool.
These three practices are backed up by Science. This science is elaborately discussed [here].
