Guffaw. What guesses was I making there? Was it not socially acceptable once upon a time to badmouth certain ethnicities? Have I guessed that?
Nor am I speaking for any group. I'm commenting on reasons why a division is in place with this particular community that leads to it further separating itself.
Expecting to be treated as an individual is all fine and well, but if others treat you as a single entity, and negatively, folks are inclined to band together, and some are indeed likely then to live up to the stereotype imposed upon them. This is hardly a questionable observation.
EDIT: And by all means answer my question. Because if those things weren't ok, I'm curious why we shouldn't care about the same type of opinions being held about travelers?
