We aren't all from multi racial back grounds. I don't have any black,mexican or any non white people in my family tree back as far as I can trace. (back to Scotland before they immigrated here a few hundred years ago)
Nor can it be said that it's hard to have pride in your heritage because alot of people have so many different kinds of people in their background. (not color wise but country) I bet alot of the people that have posted don't have other races in their bloodline.

On the american pride issue that doesn't matter what color or creed you are. It really doesn't matter. I know blacks, mexicans, asians and indians (feather and dot ) that have pride in this country so it really doesn't matter where you are from. If you are an american then be an american not and african american or any other form of american.

As quoted from Teddy Roosevelt
In the first place we should insist that if the immigrant who comes here in good faith becomes an American and assimilates himself to us, he shall be treated on an exact equality with everyone else, for it is an outrage to discriminate against any such man because of creed, or birthplace, or origin. But this is predicated upon the man's becoming in very fact an American, and nothing but an American...There can be no divided allegiance here. Any man who says he is an American, but something else also, isn't an American at all. We have room for but one flag, the American flag, and this excludes the red flag, which symbolizes all wars against liberty and civilization, just as much as it excludes any foreign flag of a nation to which we are hostile...We have room for but one language here, and that is the English language...and we have room for but one sole loyalty and that is a loyalty to the American people.
