Re-read your post. You don't see anything wrong with it?Are their Cubans who are racists against Blacks? YES, and I have met a few. While many Cubans have some, or alot, of black heritage, many do not and some of those make a point of being 100% white.
But I also know some Mexican-Americans who are racist against blacks. When I was stationed in Hawaii back in the mid-1970's I had a crew chief who was a Mexican-American and I accused him of being Puerto Rican and he would get mad. Over Christmas I noted he was moping around and I asked him why he was so blue and he said his wife had gone home for the holidays. I asked him how much it cost to send her back to Puerto Rico and he almost hit he.
He said it was bad enough to call him a Puerto Rican but even worse to say his wife was. I asked him why he was so upset and he said "Those Puerto Ricans are half-n*g*rs".
I have found out that a significant number of white Hispanics are prejudiced against blacks. But I also know many blacks are racist against whites too!
Your incessant talk about racism, where you perceive it to exist, all the time ignoring your own inbred feelings towards minorities. Why would you taunt this guy by telling him he was Puerto Rican? racist traits. Your unsolicited musings on racism are worrisome to say the least.
