I will write to Zack Polanski about this. I don't know if he'll even see my message in the deluge he gets, but we have to keep trying.
(I recently wrote to my local Lib Dem MP and Ed Davey about his disgusting gaslighting re Maccabi, and the local Lib Dem put in writing his disagreement with the party leader, ... small cracks... small steps..)
I think this is a multi-front effort requiring multiple skills.
Some will be good at migration, some will better at advocating, some will be better at spotting bad admins
Some will have the fight in them to hold bad admins feet to the fire - something we can't give up on, because that is like asking black people to find another restaurant that isn't so racist
I saw a few days ago that hachyderm was welcoming Palestinian voices.
Reading your post I think I sense the incendiary anger at this injustice that I and others feel several times a day.
I'm very certain millions feel it.
I'm also certain that this righteous anger and desire for a true "Never Again" will result in a political earthquake.
How and when that will happen, I don't know. But it has to happen. Humans can't live generations with such dehumanising injustice - both as victims and as observers.
