However, FIRST, i would like you to understand that the ethnic identity known as “the Jews” is not now, and never truly has been, defined by genes. (Or, as the ignorant like to say, “blood”).

The Jewish people - the Hebrews, the Israelites, the Judeans, etc. - have ALWAYS been open to accepting, as FULL members, people from (literally) all over the world

So we dont use “genes” to determine who is or isn't a Jew, even though our custom is to marry “in”, and having a Jewish mother makes any child a born Jew.
