travel historically has been very limited.......
Migration has always been part of, and in fact played a role in, human evolution and all the history that has followed. Human beings have always and everywhere 'mixed' whenever the opportunity arose. Take a look at those Neanderthal genes you have (you want to talk about real "race mixing," there it is). Science and History prove my point.
Part of your premise is correct; we are a nation of immigrants. However, the part you are leaving out, or I didn't see in this thread, is the fact that immigration should be controlled in order to prevent chaos, disease, disruption to an economy, among other things. If a nation is to survive it must be able to manage, and KNOW who is in the country. This is not being done, and our "admininstration", which I mostly regard with contempt, is blind to the dangers such unbridled influx of people into the US brings.
Thus, as a citizen of the US, born and bred (my ancestors were here BEFORE we became a Nation), I resent both the influx of ILLEGALS (and that is what they are no matter what the bleeding (and bleating) hearts say, and those who would HARM us by allowing it. Before the same bleeding hearts start screaming "racism", "hate", and "bigotry", I will say my objections to people flooding our borders is NOT based on "race", OK? I don't CARE if you are a little, green man from Mars, just now parking your saucer, if you are have
permission to be here, I say, "Welcome. Have a nice, life, or stay, etc." If you SNEAKED across our border(s) without such permission, visa, work permit, green card,
YOU ARE A CRIMINAL BY VIRTUE OF HAVING STEPPED FOOT IN HERE. I don't WANT you here! I don't want your "anchor" babies staying here, either. (We'll address that, perhaps, in another post) I want you rounded UP and sent back wherever it is you came from. I do NOT respect those who slip in here to take advantage of the system, milk the welfare system, or take jobs from teenagers at Micky D's who ought to be taught a WORK ethic anyway. I have already been victimized, both BY their illegal actions, AND directly by being STRUCK in traffic (rear-ended) by a carload of so-called "immigrants" (they are NOT "immigrants"--they are CRIMINALS). They attempted to RUN, but a Honda Civic couldn't outrun a good old American V8 Chevy, and I got their tag #. Did ME no good, tho---no license, no insurance!

Again, these people are not "undocumented 'immigrants'" like the drippy, hippy liberals say, eager to BUY their votes with lush, flowing welfare benefits:
THESE PEOPLE ARE *CRIMINALS*!!!
Finally, I do NOT want to "Press 1 for English" in my OWN native land where English is the predominant language.
WHAT is
that all about anyway?

When Italians, YIddish, French, Germans, came, we didn't have to "Press 1". So why can't the "Hispanics" Press 1 instead?
If you are a legal
immigrant, a naturalized citizen, have permission to be here, I welcome you so long as you obey and respect our laws. Remember: As a visa holder, green card worker, you are a GUEST here, and if you are out there "demonstrating", putting a foreign flag OVER ours, putting the US flag upside down (a false distress signal), I want you KICKED OUT, NEVER allowed to return. That does NOT make me want to welcome you; it makes me MAD!!!!
