Similarly to your argument that parallels to an Ukraine don’t strengthen his argument, I think claiming parallels to MLK is far more invalid: riots as the language of the unheard? sure. Rape, torture, and murder of civilians including children? Then parading the naked, stripped dead bodies through the streets? Surrounding a peace festival literally devoted to calling for peace and reconciliation and murdering them? And these are just the things Hamas have themselves uploaded onto the internet for their supporters to jeer at. They’re proud of it. Nah I can condemn that pretty unequivocally without invoking MLK’s “language of the unheard”.
(edit: I just want to add that I understand that you don’t support what Hamas is doing, but I strongly feel that even invoking the parallel of MLK’s words on unrest is not appropriate here either.)
Just to be clear: I agree that Israel and especially its nearly continuous succession of far right governments the last (edit: almost) 30 years (since Rabin’s assassination) deserve condemnation for ethnic cleansing, apartheid, “collateral damage”, and just outright murder - including of a journalist by security forces earlier this year.
