You will choose not to believe this, but a lot of people find the idea that anyone, regardless of the color of their skin or where they came from, could come here ILLEGALLY while there are people waiting in line to enter through the process that, you know, our country's laws set up a little ... unfair.
My personal view is much more nuanced than that, but I can't debate someone who thinks opposition to illegal immigration is entirely a racial thing. It's just not.
Well some of the opposition is just plain garden variety stupidity. The same people screaming about illegal aliens are the same ones using them for childcare, lawn care, cheap food, etc. Mitt Romney anyone? Give me a break no one wants a college educated motivated immigrant with their same skill set... only better and cheaper. They want an uneducated guy or gal to use as cheap labor and blame for every crime and in the end torch them for fun/political gain.
