In truth, Spaniards really do despise hispanics tho. Even when Hispanics look white, the minute they open their mouth to a Spaniard, the secret of their origin is revealed.
A Dominican showed me this. When I was last at Heathrow, I struck up a Convo with the white-looking cab driver . once he realized I was American and he wanted try some Spanglish with me.
My first question to the dominican cabbie was why he was in England and not in Spain; which I assumed at the time would be an easier switch for him. He lamented to me that he tried living in Spain but faced such an extreme discrimination that he had to leave. The Dominican couldn't even get employed in spain. He was overjoyed that The Brits in London treated him better than his cousins in Spain.
Those "me no black, papi" mind-games only work in the Caribbean. When Hispanics join actual Europeans(or their descendants); they cannot claim white.
