The question is, is this really true.If you let the balance of power fall too far to the state, it's grossly naive to think it wont lead to use of that power over you, your friends and your children.
Consider for a moment. Do the supporters of oppressive regimes actually suffer under them? Is it not the case that those who tacitly or overtly support this kind of power imbalance actually benefit? Certainly a minority of top supporters do, but what about the silent and not so silent majority that prop up the regime? Does their support not in fact, pay off?
Are registered Republican voters who attend church every sunday, protest against abortion, call for lower taxes and "family values" really going to suffer under these DHS policies? I invoke Godwin because it is inevitable. Look at 1930's Germany. If you weren't communist or jewish, then you, as a german, probably did rather well under the Nazi's. Why wouldn't you support them? It's not like you valued abstract concepts like "freedom" and "democracy" now did you?
Most americans, no, most people in the western world, do not value these concepts. They support internment, executions, secret trials. I'm not being rhetorical here. As long as you mention the right groups; terrorists, pedophiles, minorities, lower classes, etc, the average joe will not see their freedoms as something worth valuing anymore. People do not believe in universal rights for all, only in rights for the right people, which of course includes themselves. It's sad, but that's the way it is.
Which is why it's so easy to fall in the "think of the children"-trap. You always think it will only affect the "bad guys".
