I agree with some of that. I think what you may not be aware of is the soul of a Mexican. Caballerismo rules here. They are forced by Centuries of culture to be friendly, kind, hospitable ... in face to face situations. What they say or what they think is something you'll never know. Our observations fall into what's called, the fallacy of visual knowledge.
Dood, I've been here for more than half my life. Once a Mexican gets beyond my appearance they think of me as a Mexican. I know nobody wants to hear that sh*t but that's how it is.
If you saw the Chapala video I posted a few weeks ago, the narrator, who spoke the clearest most coherent Spanish you could ever hope for, made some points. One was that only a small portion of the locals are native locals. Your locals came from all over Mexico looking for employment. Not much different than those who go to the USA.
Why aren't street dogs human-aggressive? They're dependant. Get my drift?
Doesn't matter what the people think of us, it's the analisis the government heads have decided what's best for them, not the nation, them. As much of the USA is worried about the browning of America maybe the government here is worried about the whiting of Mexico.
The people want your cash and some want your cash and whatever you bring that would make their life better. Too bad they don't represent the ruling body.
