An assertive gesture by our Hispanic population and I'm glad to see it. Many of you know Spanish but just in case, aqui estamos means we are here (so get used to the idea). No nos vamos is literally we are not going. Here, I think it would be better translated as we are not leaving.
Part of the genius of this country is that our residents are from, well, everywhere. I grew up in the most ethnically and linguistically diverse county in the nation, Queens. (So okay, Trump's from there, too.) Sometimes the blending process was full of conflict but I, for one, welcome everybody.
