Re: Is this time to go home?
Oddly enough, the movie "Seige" actually dealt with this issue long before 9/11, and is worth renting if you can find it. In any free society we struggle with how to balance suspicion with freedom. In the case of "terrorism" and the Japanese, the threat was an unseen one. In the case of Japanese of course they were worried about spies, and there was some evidence that many members of the Japanese consulate in Hawaii actually scouted out Pearl Harbor in advance of attacks, as some terrorist groups have done prior to attacks.
My advice for citizens and visitors alike is to hold your head up high, help the authorities if you are able, engage your Gora friends and openly discuss the issue, and be patient with the paranoid. I think that you will find that if you calmly discuss your fears and your situation, that most Americans will be sympathetic, even protective. If in the next breath you rant about Israel, and shout "Kill the Jews", you may induce enough perspiration to cause trouble. There is a time to discuss your rights, and a time to express your political views. Both are appropriate, but discussing them in the same breath mixes messages. Stand firm, hold to your rights, do not run away, and do not hide. This will pass.
I did engage a gori who erstwhile was a friend but then couldn't be patient with her paranoid and hence here I am- single again :)
