I was making a point about you using a racist term. It's not nice, is it?
"gringo" isn't comparable to "wetback" in any way. the former is a term to denote american and western culture or people associated with it and usually has a neutral connotation whereas the latter is a racist slur used by rednecks to refer to latin americans immigrants in particular but also people of latin american origin in general and always has a negative connotation.
And yes, I do hope you get banned but considering the quality of the moderation around here, i wouldn't be surprised if you get a free pass.
This from wikipedia:
Gringo (pron.: /ˈɡrɪŋɡoʊ/, Spanish: [ˈgɾiŋgo], Portuguese: [ˈgɾĩgu]) is a slang Spanish and Portuguese word used in Ibero-America, to denote foreigners, often from the United States. The term can be applied to someone who is actually a foreigner, or it can denote a strong association or assimilation into foreign (particularly US) society and culture.
In Spanish it does not have a negative connotation. Roger Axtell, a travel etiquette expert, notes that "[t]he word gringo is not necessarily a bad word. It is slang but is derogatory only in its use and context."
The word was used in Spain long before it crossed the Atlantic to denote foreign, non-native speakers of Spanish.
