Ah yes. The old "it's just like the Irish" argument.
Did Ireland have a centuries old claim on North America?
Did they lose it in a war against the same people they came to live with?
Did they come in such numbers that they literally outnumbered the people whose country they came to live in within 1 generation?
I could go on and on. But safe to say your analogies fall apart under even simple analysis. And for those of us who have had to live with the real effects of this hostile, vicious, hate filled invasion from a brutal and corrupt society - like having members of our families assaulted, kidnapped, almost murdered (like mine) - your soothing, cooing words ring ugly and empty like the cheap salesguy you are.
By the way...one of the first rights of any democracy is to decide who is part of that democracy, the right of free association. As far as "These are people who came here to stay", when did we vote to have them stay with us and ultimately demand to rule us?
In what way are Americans free when Mexicans vote in their elections, occupy offices in our government, even become police because of sickening, un-Constitutional preferences for them over us?
You obviously have an agenda. And that agenda is, "don't worry little people, everything will be alright when we take over. You're gonna enjoy working for us, just get used to it...". So you're busted, pal. A liar with an agenda is all you are.
And as for this statement:
they tend to form mafias and street gangs
My family(s) have been here for going on 3 centuries and they are still, for the most part, the same Protestant, honorable rural people that they have always been since they stepped off the wooden boats that brought them. I know of no generation that went through this "phase" you claim is normal. They came from civilized societies and they remained and remain civilized.
It was only when we went weak and allowed in the un-Civilized that the phenomenon you speak of occurred.
It must be terribly hard to be so bitter.
So, you say that members of your family have been attacked, even murdered by Mexicans? Tragic. Lots of people feel the same way about black Americans. But if you assign individual acts of violence against an entire race, your injury is far deeper than a physical one.
And yet, onto your other arguments, history well establishes what I said as true. Indeed there have been Italian, Irish, German, and Jewish gangs and mafias, all related to waves of immigration. But over time, assimilation and integration has tempered much of that problem.
No reason to expect different from Mexicans. And, BTW, only a tiny fraction of those living in America join the Aztlan movement, embrace la raza as such, want part of America to return to Mexico or secede, or other such nonsense promulgated by nuts.
Teddy Kennedy, I might add, wanted the US to abandon Vietnam and invade northern Ireland to drive the British army out. You know these Irish immigrants, so hot headed.
