I don't think you're being fair here. Law enforcement has trouble crossing national borders, for one thing (especially in the case of Mexico where organized criminals have outright bought off lots of politicians). I don't think people who look at big drug-related massacres in Mexico on the news and feel worried about cartels entering the US are necessarily bigots.

> And by the way, you can get smuggled into the US via the Mexican borders for like a couple thousand bucks. There's a whole industry around this. The people who do the smuggling are called 'coyotes". Any serious terrorist is already here, via that border.

You're making this sound easier than it is. Lots of people die trying to do this now.
