Probably you mean "spaniards" or "spanish people"
Nobody will "hate" you for being "anything" in Spain...
I don't think they will point at you and say: "Look! A mexican mestizo! Let's hate him!" ha ha.
I don't think they even know how a mestizo really looks like...
Spain is a very touristic country and they are used to visitors from all over the world.
In fact, it will be easier for you because you speak spanish !!
The mexican-man is delicious for the HOT-PEPPER that He has.
The color of the skin, eyes, and hair...is not important...at all.
LOL
Yes. If they behave themselves.
I wet to Spain and I'm Mexican. My friend said I would be hated on cos I'm Mexican. I wasn't and he said maybe because I have light skin and green eyes. But, do they like mestizo Mexicans? Or do they hate them?
