<<Geez, how ignorant can you be not to see any of these facts?>>
I see them better than you'll ever see them. All four of my grandparents were immigrants who couldn't speak a word of fucking English when they got here. They came from the arm-pits of Europe, shit countries where they had to thank God after every Easter that they weren't among those torn apart by mobs of Christians pouring out of their churches inflamed by their ignorant anti-Semitic priests and looking to revenge the death of their so-called "God" on the descendants of his "killers." They had no rights to a decent education or job, and were kept down by prejudice and racism every fucking day of their lives.
Do you really think that they would have let any fucking so-called "law" keep them out of a better country with a better future for their descendants (ME!!!) simply because a bunch of genocidal racist bastards killed off the original inhabitants, stole the land and passed their own exclusionary laws keeping out anyone who got there after them? Fuck dat. They had as much right to exclude the late-comers as they had to exterminate the original inhabitants. My grandparents came the "legal" way although I'm sure that the "legal" way included plenty of bribes and "fixes" across the way. In the early part of the 20th century, immigration from Europe to North America was usually done by travel agents who were basically "fixers" who, paid enough, would "fix" your passage in. Forms to be filled out? Here, gimme, I'll fill it out for you. Don't tell me anything, I'll fill it out for you. NO, I DON'T WANNA KNOW how many years you went to school, the date you were born, what problems you've had with the law - - I'll fill it out for you, get it? This is how they came in, and they paid the fixer because they knew that once they got in, nobody could get them out. If they couldn't afford a fixer, they would have snuck in anyway, illegals to be sure, but better an illegal in Canada than a Jew wherever the fuck they came from. And no, once they got here, they didn't rob, steal, rape, murder, spread disease, defile the land - - they went to work, hard work, they got married, raised families, educated their kids, contributed to the economy, paid their taxes (maybe, WTF would I know, as much as anyone else, I guess) and generally helped make this country a much better place - - contrary to all the dire predictions of the racist anti-immigrant bigots who wanted to shut them out. And this goes for all immigrants - - Italian, Chinese, Japanese, whatever.
So don't patronize ME with your "how ignorant can you be?" patronizing bullshit crap. I know immigrants, I know how the U.S. GOT the land that they're trying to keep the Mexicans out of, I know WHO they stole it from, and I know what to think of their anti-immigrant racist BS.
