He didn't 'mess up' he knows exactly what he is doing. We need to get rid of this narrative that Trump is just someone who makes accidents. He is and always has been a white supremacist. If his treatment of black tenants in properties he owned didn't send red flags your way, or the fact that he has read through Hitler's autobiography and keeps a copy of it, or the fact that he refused to disavow any connection to David fucking Duke of the KKK, or his appointment of Steve Banon to his cabinet, then THIS should be what does it for you. The man is, has always been, and always will be a white supremacist.
We need to call him what he is, call out his administration, and really be honest with ourselves. He's not some misguided idiot, he genuinely holds dangerous beliefs and should be nowhere near the presidency of the united states.
