This is ... incredibly ignorant, beyond my comprehension. Basically, what you've been saying (other forum posts included): Ohh I am in another country, but who cares, I'm American! I don't have to change for the country, the country has to change for me! Those people are so weird, I'm the only normal person here.
And you expect a serious discussion?
As asked by other people: Why are you staying there then? What keeps you from going back to the US if you don't like Japan nor plan to adapt to its culture?
And last but not least: Do you like people who come to the US, don't speak/plan on learning English, don't care about culture and tradition, call all Americans mentally sick (since an OCD is a serious illness, not some kind of funny behaviour)? I don't think you're there as a bad American, actually I'd rather say you're a bad human. (Sorry, that may be a bit harsh, but your attitude is ... scary.)
