Robtard is the closest to being correct.
What Jaden is thinking of is mestizo. Mestizo's are a mixture of European (Spanish) and Native American blood. (Don't be smart asses, you know what I mean, lol.)
So, Nauj is correct in saying he is a mixture of Spanish and Mexican, if he means "Mexican" to mean "mestizo" and this would make Jaden's point a bit more relevant....he would just be a mestizo with more Spanish blood than Native American...assuming his "mestizoness" is due to Spanish ancestry, which the ridiculous vast majority of Mexicans are Mestizos due to Spanish ancestry.
You wanna know what's absurd about all of this? I learned all of that in 7th grade. 😐
And, this, folks, is why Mr. Grumpy pants want to punch me in the face...I love this kind of information, but aparantly he didn't.
