Actually I don't really think that this time, this "foreigner" thing is something orchestrated from the upper echelons.
It is something lingering in every society, and is in general just under the surface, coming out every now and then.
Don't need to remind anyone here about historic cases of racism surfacing in their own country, right?

Frankly speaking, I can even understand the public reaction on cases like this guy in BJ, harassing girls in the subway and later on the street.
And the totally unacceptable behavior like that idiot in the train, or riding a motorbike in flip-flops, does all not help, and only acts as fuel to the fire if it happens at the wrong time.
Be honest, if foreigners do that in our home, the world is also too small for the storm of protest.

Just my 2 cents on the "other side" of the story.
