 Also, what is the purpose of characterizing the problem as "dirty Mexicans"? (quote "most notoriously dirty Mexicans in the USA without legal sanction"). There is a link using that title to a nonexistent article. Was this adjective intended as a mention of a stereotypical name often used? If so, it should be marked as such, with quotes or "so called..." Otherwise, with the most open mind available, I see no purpose for such phrasing other than revealing a not-so-subtle racist intent by a biased submitter.
