I can see where this type of question can be construed as an insult. I see it like this. Many Americans wonder about those in the US of Muslim faith because it does not seem that the vast majority of them have rose up and state - hey, we are not a part of those who want to kill you. With certain organizations within the US that loudly talk about annexing parts of the US back to Mexico, with Vincente Fox encouraging Mexicans to illegally cross over, with the Mexican army guarding their southern border; the rest of America does not see those immigrants who want to be Americans raising their voices in protest to these actions.
The question is not asked to Italians, Irish, etc., because those groups do not have some "spokesman" demanding a part of the US to house Italians, etc. When a black American boxer is fighting a white non-American boxer, I do not cheer for the white guy. I cheer for the American. When Americans see an Hispanic team cheered more than the American team in a soccer match, something is wrong.
Did we NOT already have this argument, back in '76? (1776, that is)
How about the 'Civil War' / 'War of Northern Aggression'?
Were not the same things asked?
Our Government locked UP people who LOOKED like the enemy in that war!
And how can we forget the suspicion and ostracism with which the German citizens of the U.S. were treated during World War I (much more so than in WWII, when everybody was more worried about Japanese subs and saboteurs, and the Germans had been better assimilated). Remember "liberty cabbage"? Remember Frick's daughter who refused to allow German art in the Frick Museum? "Which side are you on?" was asked of Germans every day at that time, and they were reviled in the newspapers and in fiction.
My tag line seems particularly appropriate here. This guy is whining. He needs to grow up and take the long view of history. AS SOON AS his people assimilate, this problem will go away. Not before.
