Personally, I think CLEAR is a bunch of BS. Sure, you can get through the line sooner in some airports. But is just handing over your rights on a silver platter worth the cost?
This is what our gov't is best at these days. Acting as though certain things are law, when they're not. Then, once the vast majority buys into it and stops questioning, they make the unlawful lawful.
I STRONGLY urge everyone to reject CLEAR, and go about flying as usual.
