Why don't the Japanese differentiate more between foreigners ?

I don't mean to put you on the defensive, and I'm sorry if it sounds that way. I used to feel very similar to how I think you do, so I'm just trying to help you find a less stressful approach to your situation.

I understand and appreciate that. I was not on the defensive, but just explaining the things that naturally flow through my mind in such situations. Sometimes I tell myself that either this or that person is racist/xenophobic or I really can't understand how they think. Either way it makes me feel somewhat nervous or insecure (or even angry).

I feel the same way.
