Ignorance by itself is problematic. Ignorance coupled with aggression compounds both of them by at least 100%.
What I find especially egregious is that an astonishingly common form of prejudice in the USA is directed at people of Hispanic background. It boggles my mind when I encounter people who manage to ignore the fact that the map of North America includes Mexico, Hispanolia, Haiti, and Central America
Yup, Mexico is a North American country. Vitriolic and ignorant as any misperception can be, the one that disallows Mexico's actual geographic place is one that's become way too common. It totally boggles my mind to hear people called "aliens" because they speak Spanish. Could we get a grip on the skinny here , please?
The skinny is: North America was colonized by Spaniards before it was colonized by speakers of English and French. Spanish-speakers continue to live in Mexico, the USA and Canada, Hispanolia, and Central America. Mexico is most assuredly part of the continent of North America; therefore Spanish definitely was and remains the first (or second, in the case of people of mixed Native + Spanish ancestry) language of a good many (if not most) North Americans.
But given the topography and geography of this North American continent, it probably shouldn't come as a surprise to find there's a great deal of suburban sprawl as well as very densely settled urban centers with huge populations. Some recent attention focused on suburban settlements has been leading to some promising developments for those who care about sustainability. Good for all, good for one, to be concerned about that!
