The European equivalent to Latino is Arab. It's a category of people based loosely off geography and language with a diverse range of people.
People who dismiss Poe as white also tend to be people who aren't particularly globally aware. The idea that Americans (people from the US) clarify that Poe is Latino because they are super concerned about race is petty dismissive of over a continents worth of people. Obviously you are going to be more familiar with the countries near your own, but still.
