Bowzer, you wrote,

Neither, though, should we project our fears. I understand you are very worried, but the scenario you are describing seems very unlikely, at best. You are absolutely correct that thousands of US citizens of Japanese extraction were sent to internment camps during WWII. This was unconsitutional; despite the fact that Japan had attacked the US & drawn the country into a war so many wanted to avoid, these American citizens had committed no crime.
But this was not repeated in more recent times. After the 9/11 attacks, the US government did not indisriminately round up Saudi or Afghani nationals, let alone Muslim-Americans. This despite the fact that most of the highjackers were Saudi nationals, Osama bin Laden was from a prominent Saudi family, and bin Laden was then hiding in Afghanistan.
Now the US is at war in Iraq & Afghanistan, yet Americans from these countries have not been indiscriminately rounded up by the government & sent to internment camps. True, Muslims & others have been discriminated against or attacked, but these are individual crimes; the US government does not sanction these crimes but prosecutes the perpetrators as it would any other criminal.
This is very different from the situation in Europe during the times you mentioned.
Please keep in mind as well that although there are many citizens in this country who do not wish Jews well, most of them do not like African-Americans (or Muslims, for that matter, for those who still believe Obama is a Muslim) very much either.
