My understanding is that the entire concept of a Latino designation is so vague as to make it effectively irrelevant in any sort of meaningful sense. An extremely wide range of people, from wildly different backgrounds, publicly define themselves as Latino. Carmen Electra, as an example does, as do many people whom you might think of as 'white' or 'caucasian' if you were to pass them on the street. It appears to be a "if you want to call yourself Latino, go ahead" sort of designation.
