A growing movement to go to prison? I suppose if a large enough proportion did it, they couldn't build prisons fast enough.

This is why I say to wait and see.
But I can imagine huge numbers of liberals refusing to fund Israel. It could become a massive movement. I'd keep an eye on it.
I don't think you're giving the american corporate run prison system enough credit.
People don't realize that they don't have to refuse to pay tax, all that is needed is a large enough contingent that stops buying the bullshit. Case in point: mandatory vaccination failed for the same reason.
