I dunno what to say honestly. Dirty for whom?
Not for Mexicans, that's for sure. We're proud of being Mexicans, no bullshit about it.
It's the freaking correct patronimical, ain't it?
Now, if I was a Salvadorean... I wouldn't like to be called what I'm not.
If any one called me Salvadorean, or Chilean, or Dominican, with all due respect, I'd be really pissed off by their ignorance and lack of tact.

Then there are these stupid "politically correct" people, who -scared of their own prejudices- try to change the language.

In 2004, a survey about
American citizens of Latin-American descent showed what they preferred to be referred as:
California:
[Country of parents' origin]: 55%
Latino/Hispanic: 24%
American 20%
Texas:
[Country of parents' origin]: 43%
Latino/Hispanic: 33%
American 22%
New York:
[Country of parents' origin]: 66%
Latino/Hispanic: 22%
American 12%
New Jersey:
[Country of parents' origin]: 62%
Latino/Hispanic: 23%
American 12%
Florida:
[Country of parents' origin]: 62%
Latino/Hispanic: 18%
American 19%
I imagine that non-US citizens (illegal in the US or not) prefer to be called by their nationality that by any other in a bigger percentage.
So... unless things have changed a lot in these 5 years, I'd say it's safer to call any Latin-American in the US by his/her parental origin than the funny-sounding "latino-hispanic" usage.
