C'mon, Zachary; you're a bright boy. You know that a fistful of anecdotes still doesn't add up to proof of systematic bias. All it establishes is that there's more than one individual prejudiced against Mexicans in the USA. (Not exactly a shocker in a nation of 306 million people and counting.) It doesn't really matter too much what biases particular individuals have unless they're backed up by societal institutions.
I understand where you're coming from, but what the handful of articles is meant to demonstrate is not that there's a unilateral form of racism being propagated on every level of society, but that an underlying problem exists, socially (and for some regions, jurisdictionally, economically, and politically), and that this issue has also attracted both the media and for people to act against this racism. Being "Mexican" is, simply put, not the same as being "Canadian". As a Canadian, racism on some levels exists, but the likelihood of any related beatings or murders related to your ethnicity, language, or whatnot is extremely unlikely to happen within the United States (heck, the terms 'racism against canadians' or 'anti-canadian racism' are seldom used). Should population, immigration, and/or proximity be a factor, then I dare challenge you to find equally comparable racism, to the same extent as that of Mexicans, in America against Canadians. Also, the fact that some places have racism within state institutions is an issue apart, and it disregards racism that occurs within non-state controlled institutions, and also disregards the entire social aspect of racism. If we can separate religion & religious doctrines from the State, then we can just as easily separate people from the State. Creating a law or a Constitution doesn't mean that that law/constitution is enforced, and this is something that many countries are criticized for.
You certainly haven't made the case that it's worse than, say, institutional discrimination against Copts in Egypt or South Asians in Qatar (which is how this tangent came into being in the first place).
I don't see you're point with this, I never anywhere stated that racism alone
other listed countries. To requote myself, "[The United States] fails on just as many levels as many of the countries you listed therein". If you honestly want to talk about institutional racism, then read Institutional Racism
, by Shirley Jean Better, and then Race, gender, and punishment
by Mary Bosworth and Jeanne Flavin (summary concerning Mexicans at ~p57).
