I imagine the results would be pretty much the same no matter which claptrap bag of anecdotes were used.
I believe we are all racist in one way or another as we all greedy and selfish in some shape or form. Some of us fight against these base instincts while others happily marginalize people based on skin tones and other ethnic differences.
That said it has to be accepted as a reality that particular nationals do not always fit well into new environments and locals vis a vis their own culture find them difficult to deal with.
It is not up to the locals to change their values to accommodate these differences. It is up to the visitors to acquaint themselves with and respect local customs and norms by changing their behavior. Those that don't should be shamed and ignored.
Not everybody from these countries behaves badly but unfortunately a lot do which sadly tarnishes all of them. I try to treat all individuals irrespective of color or creed with respect until I find he or she doesn't deserve that respect and believe me I have met just as many white dickheads as brown dickheads.
