If they were learning English as well as you say, there wouldn't be Spanish language options all over the place. I'm old enough to remember when that wasn't the case.

Hispanics aren't a race. There are ginger Hispanics and charcoal black Hispanics. They also come from many different countries. I know blacks did, too, but they integrated among themselves to a greater extent than Hispanics. There is less unity among Hispanics because of these things.

There is resentment there, too, anyway. See La Raza. It will get worse over time.
