Amico mio,you kinda sound like a Sardinian supremacist, lol ... I kinda like it. Anyway, sadly, you fell right into my first guess.
First of all, "terroni" is a term coined by the very people who nearly wiped out the Sardinian language, and it was never used to refer to central Italians. In fact, Sardinians themselves were lumped into that category. Also, Genetically, Southern Italians closely resemble ancient Greeks, aside from an estimated 10% Middle Eastern admixture (levantine)
oh no 'mate' look at those middle eastern myceneans ... maybe Achilles was a Sheikh afterall...

Back to my own results… You do know that the coasts of Sardinia were under Punic rule, right? Okay, maybe I’m not as "pure" as you are ... I’m guessing you’re Barbaricino or something? That’s cool, I respect that, but in which world that makes me not half sardinian? you are not fully nuragic either since you have like 5% steppe if we want to be 'pignoli'.
One last thing ... G25 is a recreational tool. It’s not used by scientists or anthropologists in any official capacity(contrary to qpadm). In fact, components like Levant vs. Barcin/Tepecik or Iran_N vs. CHG can easily get mixed up. Even the testing companies (like MyHeritage, Ancestry, etc.) can give you slightly different results, depending on their models and databases. So yeah...don’t bet your life on those numbers, okay?
A si biri!!
