its a hard issue to read. myself, being in NY, most of my latino neighbors and co-workers are from cuba, puerto rico, dominican republic, etc. and they agree with your sentiment. but not being in the southwest where there is more of a mexican/central american demographic, is the opinion different in that block?
Believe me as a Puerto Rican, how we are viewed and how we view other Hispanics would surprise you, the amount of dislike, envy, superiority complex, and other factors would astound you, we are not of a like mind, trust me.
