Never once did I say I have a problem with how you handled yourself. You did a fine job there. I said I have a problem with you APPROVING of the checkpoints themselves. And then trying to draw a distinction between 4th amendment rights and checkpoints for "illegals" as somehow being different. There is no difference. Checkpoints are checkpoints and they are illegal. You're supporting an illegal action because you hate illegals more than you hate checkpoints. Just callin a spade a spade. Cutting off your nose to spite your face...
Now wait a minute!!!! Don't you DARE accuse me of hating illegals!!!

That is a bunch of crap and I'm sick and tired of people who have no legitimate argument pulling out the race card.
On a practical level, the checkpoints do nothing at all to stop illegal immigration. The "mules" and "coyotes" know where the checkpoints are. Instead, protect your 4th amendment right to not be stopped by police for no reason and instead advocate the dismantling of the welfare state. The welfare state is why they come here.
This speaks to your ignorance of illegal immigration and border security. You remind me of people who have no children advising and criticizing those who do on their parenting skills. You've already admitted you don't have to live with what we in the southwest have to endure so you really don't know what the hell you're talking about. Before you go spouting off that checkpoints are useless you should do a little research into it - you'll find you're dead wrong.
As much as you'd like to make this a black and white issue, it isn't. Your puritanical philosophy on what violates my privacy is only that and nothing more. Whether you like it or not there are shades of gray where this is concerned. Fighting to shut down our socialistic programs is all well and good but that alone won't stop illegal immigration. For years as a young person, I worked in the restaurant business along side many illegals. I learned to speak spanish fluently and became friends with them. They didn't collect social services or entitlements of any kind. That is the case in many other fields as well such as construction, landscaping, ranching, farming, trucking, manufacturing, factory work and so on. They undercut the going labor rate and push Americans out of these jobs. Then they send their money back to Mexico to the tune of 30 billion dollars a year. Many are criminals who are running from the law in their own country and come here and commit crimes here, get caught and end up in our prison system.
This doesn't even include the discussion of enemy invasion. Do you have any concept of how easy it would be for the Chinese to invade us through Mexico? As it stands right now they have some 12 missles pointed right at the Cali coast. If they shot them off and simultaneously invaded from the south, which anyone can do now, we would be done for.
You can go ahead and live in your la-la land pretending like illegal immigration doesn't hurt our economy, and that an unsecured border doesn't put us at risk, but as for me - I'll live with the border check points for now until they secure our borders like they should. And, at the same time, I will continue to insist that they provide probable cause before they search me or my property.
