Personally, I see very little wrong with that.
What ideology and ethnic majority built the U.S. to what it was? Since the initiation of "diversity" what has happened to the U.S.?
Diversity is based on the root "diverse" which, in the case of socio-economics, means separate. We live as divided peoples because of diversity not in spite of it.
As for "immigration" there is no country on earth that is more open than us. That, too, has gotten us into trouble. We accept people regardless of their beliefs and loyalties. Today's "immigrants" don't have a loyalty to the U.S. They are here to make money.
As far as Israel and messyco why SHOULD they have a say in our politics? Why should any country have a say in our politics? That is another path to destruction: Allowing foreign policy to influence our own.
Personally, I see nothing wrong with that!
