To not criticize and desire to compartmentalize/marginalize/stamp out latin and gangbanger culture in the USA is the mark of a fool or an race/culture hustling opportunist.
Gangbanger Culture
To attempt to elevate gangbanger culture to the level of the culture that made this country what it is is an exercise in or multi-cultism. One only has to look at the social science data to see the deleterious effects of that culture on the people who live in its midst. Crime, poverty, unemployment, education...pick your metric and it will be quantifying a culture of failure and inability to cope with modernity.
Latino Culture
There are two primary subsets of latino culture in this discussion: that inside the USA and that in Latin America.
The latino culture in the USA has portions of it that can be considered gangbanger. Usually, the longer the particular individuals have been in the USA, the less likely are they to be in that latino sub-culture (with the exception of second & third gen immigrants, who are less law-abiding and less employable than their parents/grandparents). Unfortunately, the US latino culture is moving toward the black underclass culture, rather than striving for (as Rev Wright would say) "middleclassedness." It would be better for the USA and those in this partcular culture that it be stamped out/subsumed rather than add to an already hard core of poverty and failure.
Latino culture outside the USA is somewhat more diverse, as it encompasses not just the under/lower/lower-middle classes, but the whole class spectrum*. The outcome of such culture is nothing to write home about, given the history of Latin America. Wanting to stop the spread of that culture at the border is not only smart, but moral. That is, if one has reverence for the COTUS, the concepts of liberty & individualism, honesty in government service, rule of law, and an antipathy to oligarchy & dictatorship. Make no mistake: governments of nation-states are expression of / functions of that state's culture. To express antipathy toward them or to work assiduously to avoid their manifestation in the USA is showing one has judgment and doing the good/hard work of civilization.
The Difference Between Race and Culture
(This ought to go without saying, but my sig line is in effect.)
Race =! Culture, especially here in the USA. There are whites, blacks, asians, latinos, etc. who are part of the gangbanger culture. They are all equally debased and humped. All that differentiates them is superficial, considering the weight of gangbanger culture.
The same goes for the brighter side, as the many examples of successful minorities demonstrate.
Same thing with latino culture. It is a race thing only to those who don't understand it or can't see farther than the illegal aliens cutting their neighbor's lawn, who are disproportionately skewed toward one of the latino racial sub-demographics. One has to only look at two examples: Mexico & Cuba.
In Mexico, the political leaders and oligarchs are of pure Spanish blood (limpieza). The lower classes are almost exclusively of mixed or whole indian blood. In Cuba, the leadership is also limpieza, but the lower classes are black (as are a great number of the dissidents the Castros have imprisoned).
* Though it is bimodal rather than a normal distribution like the USA.
