I think that a lot of people are irked by the sheer inconsistency of the American culture: celebrate your immigrant heritage at the same time you protect “your” American land and keep those pesky immigrants out. Not personal.

There's a depth to what you're saying that I don't think you're truly aware of..."flooding the block" -- or the mass importation of immigrants to build a political machine -- has been part of my country's politics since the Tammany Hall days (political machines). Tale as old as time in the US and it's one of the reasons why there's so much skepticism. Like what you said here, we KNOW how this works because at some point we were the Irish\Italian\or Mexican that got shipped in. We're not blind to party politics and ginning up house delegates or patronage politics.

Really so its okay if a Canadian, Australian or New Zealander does it?
