oooh, scary. There are "illegal aliens" in our country. Not only are they different (because they're alien), but they are breaking the law.
Everyone breaks the law. There are so many laws out there that it's probably impossible to go more than a week (if even a day) without breaking at least one law. So using the justification that "they're breaking the law" to need to go and round them up is just dumb. It turns out, illegal aliens are only 1/4 as likely to do real crime as regular Americans. So what's the big deal?
Oh, and I'm all for them protesting (I just learned that our cafeteria didn't use real plates on Monday - likely because their dish washers were out), but the idea that a day of not buying things (even if nobody did it) would have a real dent in our economy is silly. People would have just have bought more the day before or after.
What they should do is not work for a month. Now that would cause real damage.
