They are, objectively, useless for ending apartheid. They just offed themselves rather than do anything material against it. And if they chose to not do so, they are hardly great allies. They are not on the front linea disrupting the genocide, that is left to teenagers and certain kinds of Orthodox tendencies.
But this is all really missing the point. Placing so much priority and focus on rehabilitating what are basically Nazi SS members is basically just white supremacy and sympathy for fascists. They are in no way the allies of the oppressed, they are literally the opprrssors. If you want allies, look yo those who actually materially oppose the grnocide.
You better be out there fucking defending Hamas, who are infinitely more proactive in the liberation of Palestine, guilty of far fewer crimes, and continue to be the government of Gaza, such as it is. Any single Hamas member is more valuable and sympathetic than any Zionist entity child starver.
Can you do that or does it make you uncomfortable? If so, why more discomfort for that than for the Nazi?
