Just a reminder:
>Nick is 80% white
>He has white skin, green eyes, light brown hair
>He was born in America
>Both of his parents were born in America
>all 4 of his grandparents were born in America
>6/8(?) of his grandparents were born in America
>He is ethnically Italian, Irish, and Mexican (Spanish / indigenous american)
>He can trace his ancestry back to the civil war, and his blood has been on the soil of America for at least 150 years

Meanwhile, JD Vance's wife:
>Is 0% white
>Her parents were born in India
>Her entire family is indian
>Her kids are 50% indian

When people talk about "demographic replacement", they are referring to waves of mass immigration post 1950s from predominantly nonwhite countries like Mexico, Venezuela, Honduras (where the average european admixture is 30% or less white), India, China, Haiti, or the Middle east (Where they are 0% white).
They are not talking about someone like Nick. He is American, he is white, and his blood is tied to the soil. If you believe otherwise you are either uninformed, or have been psyopped.
