I'm not getting caught back in this, I swear, but...:
What an utterly ridiculous statement. Where are the facts in Abraham Lincoln's quote (and using a quote from a hundred and fifty years ago as supporting evidence is quite something...) or the quote directly below it? Sounds like opinion to me. And the fact that the site is anti-immigration does tend to color the "facts" they're going to choose to present. You're not going to get a complete picture.
It's really not that complicated. If you're only presenting or looking at one side of the picture, then you don't have enough "facts" to properly evaluate the situation. And that's a fact.
