Far-right and “freedom fighter” are categorically opposing though. If you’re fighting to install a far-right government, you are fighting to implement authority and counteract freedom.
I don't think fighting for freedom of your country is mutually exclusive with having far right views, also I'm not saying this about Palestinians or Hamas, but overall, the mere fact of fighting for freedom of your country isn't even remotely related to ones political views, you can be on the whole political spectrum
Yes and no. Apartheid is more reactionary than far-right self-governance. It is a fight for freedom and installation of a Theocratic reactionary government, as it is more free than their current squalor and genocide.
Neither side is "good," of course, except the Palestinian civilians getting bombed to shit.
