You're skirting around his point. American liberals don't just believe in human rights for everyone in the country--they have embraced using a strong centralized government and its court system as the way of enforcing those rights. But the side-effect of that is taking away autonomy and independence from the states, which leaves states less capable of opposing centralized surveillance.

Liberals may not want surveillance, but they helped create the power structure that enables surveillance as a byproduct of pursing end goals they do want. I think the benefits of that approach far outweigh the drawbacks, but it's important to acknowledge the drawbacks. If you give the central government more power so it can achieve X, you have to be aware of the possibility that it will use its power to also do Y.
