Okay but then if a ZKP solution is presented, that's calling their bluff. They now have one less excuse for surveillance.

EDIT: Actually do one better - tell them that for 16+ websites, you're actually protecting teenagers by keeping them anonymous.

Yeah, getting into the car with the guy holding the gun doesn't become okay because you have a great argument you're waiting to use down the road. He's already got the gun out.

We should have started arguing when he just said he had a gun, indoors, in the crowd. We shouldn't have quietly walked outside at his demand. But that all happened. Here we are now, at the car, and he's got the gun out, and he's saying "get in", and we're probably not going to win from here -- but pal, it's time to start arguing. Or better yet, fighting back hard.

Because that car isn't going anywhere we want to be. We absolutely can not get in the car right now, and just plan to argue the point later. It doesn't matter how right the argument is at all.
