Fact: If you believe "X" (where "X" is conferred by birth and not personal choice) are "God's Chosen People" you're a racist.

Now if "X" is a decision made by individuals, and one can opt in or out as one decides in their life, then no.  If you believe that a certain way of life, which one chooses and then practices, means you find God's favor, well, ok.  There's no problem there; that's otherwise known as either ethics or morals, depending on whether you believe divinity or rational thought is at the core of the expected result.

But if you believe that status is conferred by lineage you're a racist and any such delineation in employment, education, housing and public affairs in the United States is illegal.
