When a white person argues against white fragility, they are displaying it. White people who didn’t feel white fragility would say “ok, yeah, this is a real thing and we need to let go of it”.
And quite frankly, how can it be regarded as anything other than white fragility for white people to make absurd arguments-as many people who share my skin color do- that racism is made worse by people of color and those who stand with them TALKING about racism?
