Pedro Martínez: your first point proves my point, the kids come over to reunify with their parents who came here because "they couldn't make a living under their in their own dirtbag country". Call it a tomato or call it a tomato but that is what the story that YOU refer to says, on a side note it proves that even poor people know that they would be better off under a capitalistic society.
as far as your population point, I was referring to it from the viewpoint of the other side than you, I'll have to do some research but I tend to think that it falls into the "can't make a living..." as I believe that I have heard that most countries(with the exception of Asian countries) are not sustainable under their current growth rate.

As far as the gay couples, thats a whole other debate as our immigration laws (even tho they are not followed properly) have reasons for letting or not letting people in. And it is not bigotry
