You quoted the law that said nil compensation may be just and equitable. The keywords being equity is how the court interprets takings now. People are pointing at the thousands of farmers that have been displaced, this is nothing new.
Per Wikipedia:
Radical political parties, such as the Economic Freedom Fighters and uMkhonto weSizwe (political party), which have wide representation across local government in South Africa, including significant representation in its national legislature following the most recent 2024 South African general election, do condone violent, race-based rhetoric and protest action that support land seizures and attacks or crimes against farmers.[20][21][22] [23]
Note that MK are the armed forces of ANC, the thing Mandela was the leader of and convicted for.
Your opinion that it is “just crime” does not stroke with the fact it is condoned by and executed by a faction within the major political ruling party.
GenocideWatch.org puts South Africa at stage 6 (there are 8 levels). The numbers are currently in the thousands and are not stopping nor slowing down. Many politicians are known to sing songs of hatred against white people such as "Shoot/Kill the Boer” at political rallies and even on the floor of parliament. EFF and MK openly calls for genocide within their government and does so with impunity. Here is the EU asking questions a few years ago: https://www.europarl.europa.eu/doceo/document/E-8-2018-000476_EN.html
Gaza is not even relevant here, Gaza attacked Israel, they are losing the war. People die in wars, although Israel is very careful not to hit civilians while Hamas uses them as shields. You want to claim there is a parallel in South Africa, then perhaps war needs to be declared. But nobody is genociding Gazans/Israelis except Hamas.
