You sound like me with being in both worlds. I have had a few incidents of anti-gringo sentiment aimed at me in the last 6 years. But most of the anti-gringo stuff I hear is from Ecuadorean friends bitching about those who live separate. I don't hear much about the backpacking crowd from anyone, which is probably good news for you guys.
I like the quality of your reporting. What you say describes very well what I see out there. Much better than a lot of the reporting out there. Example: this Breitbart writeup about Cuenca that talks about "Cuencans," a term I have never heard used by anyone (expat or Cuencano) who has actually spent time here.
