When you hear the word "immigrant" do you think of a Mexican or someone else?
It depends on the context.
I don't think of any group in particular.
I think of my grandparents and friends.
Depends on if the word "illegal" precedes it.
I don't usually associate "illegal" with immigrants. Immigrants I see as legal permanent settlers, illegal aliens as temporary invaders, although that may not be PC...
I picture gypsies. Lots of gypsies.
I think of people from many countries, from many periods of history. And especially of the many people from other countries with whom I've worked. Almost none of which were from Mexico. But that's just from my personal experience.
I think of my Great grandparents arriving on a boat on NY after WWII. They actually did this! I'm Dutch!
