Useful – as is pretty much everything that hits the Vox site, every day.
I had a long online debate on this topic several years ago. The funniest part being the folks on the other side were Cubans who make lots of money hustling Latinos and Hispanics – which they use to support reactionary Anglos.
I was making exactly the point Terry makes in his graphic article. They were trying to convince me I qualified as Latino because the Italian half of my family was Latin in origin. A terrible abuse of semantics. They advocated that anyone who had any ethnic origin along the Mediterranean basin was Latino.
