One doesn’t need to do large-scale sociological research to find and understand what is US White racism. One only needs to look at the words of the present president.
1. He calls Black VP candidate Harris ‘a nasty woman.’ Under racism, non-Whites have only two options: to pretend all is fine or to be upset. One doesn’t need to be upset to the extent that one is consumed by anger. But if one does not buy into the ‘all is fine in the USA’ myth, one will be upset and will upset those who did buy into it. Such a person ‘is nasty.’ Compare to the non-racist sexism of what Trump called Hillary: ‘crazy’ and ‘crooked.’
2. He doubts if Harris can be VP and president because, is she really born in the US? Same as with Obama. A non-White does not belong here and their birth certificate is likely false.
3. Trump now accuses Biden of wanting to open up all borders so that every community in the US will be flooded with foreigners with corona. (Never mind that the infection rate in the US is the highest in the world, making the country unsafe for people entering.) That is racism too. Non-White migrants are not only evil–they carry dangerous microbes. This, while the Trump virus is killing a US citizen every 80 seconds–there is no need for ‘foreign’ infections. (In contrast: under Obama, Ebola killed TWO people in the whole of the US.)
4. Giving racists a pass. Claiming that no doubt some of the people chanting ‘Jews will not replace us’ must be ‘very fine people.’ You could say that in their heart of hearts, all people are very fine. But then, one should first declare every individual ‘a very fine person.’ That leniency shouldn’t be reserved for White supremacists.
5. Assuming that all Black Americans know each other. Telling the first Black woman he sees to talk to ‘the others.’
6. ‘I’m the least racist person.’ Never trust anyone who says ‘would you not trust me?’ or who claims to not be a bigot. I never had to claim I’m not a racist. Why does he?
7. There’s no protest from Trump allies. The racism bonds racist Whites, comforts them. This teaches, never to be silent in the face of racism.
You see? No deep research is needed. Trump is a goldmine for learning about systemic racism.
