Race and ethnicity in research methods Book

This book was mediocre, although informative it doesn't cover what I consider very important details regarding Mexican History and conquest. He lays out important factors and details that begin from the arrival on the Spanish(1520s) all the way the 90s, but doing so leaves out a lot of antecedent roots and causes of certain times periods. For example, he covers in very brief detail one of the most important time periods in Mexican history, the Mexican Revolution(1910-1920) he barely delves in the economic, land and the sentiment associated with the Mexican Revolution, he fails to mention important actors and revolutionaries that paved the way such aspirations. He will however regurgitate over and over how the Spanish suppression and subjugation of the Indian masses and later peasants formed the "Chicano" psyche and inferior state of mind. He will do this over and over and different forms of vernacular. This is an older book, so some of the facts are outdated and I think that Hispanics are way more resilient that Vigil gives them credit for. One fact that he keeps reinforcing is the inferiority complex that chicanos have, that stemmed from the Spanish conquest and subjugation to the Anglo conquest of the US. I completely disagree, he might be subjective on this and not quite empirical.
