I have relatives thru marriage who have not
seen SPAIN for more than 500 years but still speak the
language called LADINO which is an Hebraic form of
Spanish.
Wow, those are some old folks!

But English probably has more "yiddish" words than "Ladino."
Tracing ancestry thru linguistics is just as accurate and far more interesting than using DNA. They have distinctive customs in both ritual and song that stick
like glue. They even have very persistent cuisine habits.
Cuisine is another interesting "tracer"
My Mom enjoyed cooking up very traditional Malay dinners as well as Italian and Swedish dinners. She spoke Malay, Dutch, Spanish, French, Swiss German and English. She was racially Dutch but born in what was called at the time Java in "The Indies." Point being, DNA (objective science "reality") is obviously the most accurate way to determine ethnic ancestry.
Getting back on topic. Cortez is obviously not a Jew. Although if she takes an Ancestry DNA test, I will stand corrected. Since she has not, she is lying. But what else is she lying about? I watched a few of her absolutely insane presentations about herself. She said she doing "community organizing" -- we have heard that before haven't we? -- during the day and kind of had to get a job as a bartender to help her mother pay the mortgage after her father died. Was this house in Westchester County, NY near Crooked Hillary? Figure $3K a month for the mortgage, $2K for oil heat, insurance, electric, $1K for real estate taxes, etc., etc. That is $5K a month at least just for the house, not to mention, cars, food, clothing, etc. Which pretax requires about $100K a year salary. Folks who the fuck financed this Cortez nutcase? Soros?
