Many Palestine Actionists have gotten weak or no sentences as their targets usually dont show up in court and the actionists defend their actions as legal and moral in the face of the illegal and immoral actions lf genocide. Some judges sympathise with that rhetoric and so do juries.

Now, they won’t be able to do that because judges and juries will not be making decisions on their actions, but on their affiliation to a proscribed organisation. TLDR just makes actions more risky and organising will be heavily suppressed.
