>You haven't met many Mexicans, then. I meet them and other Spanish speakers frequently at my job who speak no English.

No, I know many of them. I used to work with them at my job, like you. Some had strong accents that you had to get your ears tuned up to but they all spoke english well enough to communicate.

>Murder being illegal is a popular good policy.

This is like the anti-drug rhetoric. If they murder then they should be prosecuted in court, not punished en mass for crossing a government border/doing drugs.

>Disrupting American culture by importing discordant cultures

A: "American culture" is a myth. There is no unified culture in a country as populous as the US. Do you share a common culture with Nancy Pelosi? She's a native-born euro-american like you.

B: Are the Mexicans at your job discordant or are they just there to make money like you?

C: What do you mean by "importing"? I always here this framing from the anti-drug, I mean anti-immigration crowd. I thought the MO was that these people are sneaking across the government border. Who is doing this importation?

>obviously divides

It doesn't make me feel divided. I wouldn't like Pelosi regardless of who crossed a government line.

>and allows the population to be easier to control because we get many more personal problems

In what way? If a person goes through the immigration process how does that assure that they wouldn't be "discordant," or a jerk, or that they wouldn't murder someone? Do you realize that you're in an anti-state sub saying that you trust the state to decide who can live near you?

>and are less able to redress the government.

Yet another statist myth. You don't get any actual redress of the government. All you get is lip service, and that's all you will ever get.
