My point was that Rosa Parks' offense, whatever the racist police's explanation for it, was indeed interfering with apartheid. There is no "contrary to the claim" there. Rosa Parks was indeed arrested according to some legal framework around preserving an apartheid, just like here. Maybe they took some time to "settle upon legal language". Maybe the police here will, too. Either way, both cases are around protestors protesting apartheid and being arrested under some charges that the apartheid-preserving powers conjured up.

To address your edit:

Rosa Parks was protesting the treatment African Americans were receiving, these workers were protesting the treatment Gazans are receiving.
