Even LEGAL immigration is a huge problem! I won't go into detail about the immigrant who bombed the Boston Marathon that we're thankfully executing (or the immigrants who helped carry out 9/11, or the immigrants who helped with the 1993 WTC bombing...)

Not to get in the way of some good ol' fashioned brainless racism, but none of the 9/11 hijackers were immigrants. Most of them entered the US for the first time less than two years before the attacks, and none were applying for citizenship.

Try heading to Sweden and saying "Hey, I have no education or skills, and by the way, I have a disease and will immediately go on government aid." and see how fast you get in.

Again, you're arguing something that doesn't exist.

I'm a skilled high-tech tradesperson making six figures a year, and I had to jump through fifteen hoops just to get a visitor's working visa that lets me come into the US a few days a month.

Also worth pointing out that Sweden accepts about 1% of its population in immigration each year, while the US takes about 0.3%.

he loves this country as an AMERICAN, and not somebody who wants to turn us into some shitty European tax-itopia.

Yeah, the "shitty European tax-itopias" are outperforming the hell out of the US on basically every measurable quality-of-life index out there. We are simply better countries than you are, and basically everything Donald Trump stands for would drag you even further behind.

The census bureau says 10-12 million, but that's just by murky statistical deductions

Yeah, basically the only people saying "30 million illegal immigrants" are the Minutemen, Border Patrol unions and Jeff Sessions. Also such notably impartial organizations as The Dustin Inman Society of Georgia.

TL;DR - you're an ill-informed racist, and that's the only people Trump has any hope of winning over.
