like first let me get it out that while i think alluras actions were wrong, and in the show itself the issue was resolved by her changing her thinking, i completely understand the emotional journey shed have to go through to essentially have her ‘side’ in the war, her safe space, invaded by what shes cleanly considered the enemy up til now

but the comparison just doesnt work!

has it not been established that telling people of mixed ethnicity that theyre ‘basically white’ or equating them with whiteness is a Bad Thing to do when they themselves may be on the receiving side of oppression and aggressions from white people? sure, keith hasnt grown up suffering galra-specific oppression, but he is in danger from them, and hes treated just like any other non-galra fighting against the empire- hes not given any kind of advantage due to his heritage. hes not in the oppressor group.

and, of course, the fact that he had no knowledge of his galran blood takes him out of this comparison entirely! he hasnt grown up in an environment where the galrans actions are normalized, where he could have pick up even subconscious racism; hes hasnt grown up in an environment where the galra empire exists at all!

if were going with the original comparison, keith (/those criticising alluras actions) isnt a man telling women ‘not all men!’, hes a non-man living his entire life with no knowledge of men and not believing he is a man and then suddenly being told that he is a man, and that he’s ‘just like all men’ and being expected to act like a group of people that up til now, hes felt nothing but unsafe or hatred around.

its not black or white- allura has an understandable negative emotional reaction that is hurtful and inaccurate and works through her issues and realizes that keith has nothing to do with the empire that murdered her people.
