No, You Can't Tell By Looking

I'm surprised. Given the attitude of many non-Hispanics in my Kentucky county, where virtually all the scut work is done by Hispanics, from tobacco cutting to housecleaning, I'd have guessed it was more like two in three, or even three in four.

One In Three Americans Falsely Believe Most Latinos Are Undocumented 

More than 30 percent of non-Hispanics inaccurately think that a majority of Latinos in the U.S. are undocumented, according to a new poll from the National Hispanic Media Coalition (NHMC) and Latino Decisions about media portrayals of Latinos and immigrants. Only about 18 percent of the Latino population in the U.S. is undocumented, and 37 percent of U.S. Latinos are actually immigrants. In its report, the NHMC said media portrayals of Latinos and immigrants exacerbates “stereotypically negative opinions” about them. “It is producing attitudes among non-Latinos that contribute to hate speech and hate crimes,” said Alex Nogales, president and CEO of NHMC. The organization plans to share its results with the Federal Communications Commission and the National Telecommunications and Information Administration to push the agencies to study the impacts of hate speech in the media.

As I always say when this subject arises: Unless you are 100 percent Native American, you're here because of immigrants so shut the fuck up about "illegals."
