Clemenza, Puerto Ricans themselves are a big mixture of intermarriage. I've known Puerto Ricans who will say they're Puerto Rican, and then later tell you they are "half-this (European) and half-that" with a "little bit of this" and "a little bit of that."
But all that is beside the point. I'm against statehood, too.
I'm just saying that PRs DO NOT generally intermarry with gringos. They remain separate, unlike most groups in this country that intermarry within two or three generations.
