I think institutional racism does happen just as institutional sexism does happen. But CRT theorists like Robin Diangelo basically say that white people are always trying to uphold white supremacy and will always be racist. It's like original sin in the bible - humans are born bad.
I think it's not true, I think it's divisive and I think it's an unhealthy way to think. If we applied CRT concepts to sex, I think patriarchy exists and oppresses women but I don't think every single man in my life is oppressing me. I mean, some have obviously, but some men in my life have been there for me in my worst moments. Conversely, I've been horrifically bullied by other women.
This lady's story is interesting as she found that seeing life through the lens of CRT to be really psychologically damaging because she interpreted everything as having to be racism. If someone didn't hold a door for her or a cashier was rude or whatever the CRT answer was this is white supremacy, not the cashier hating their job or someone being self-centered.
However, there are some things that that I'm all totally for. E.g I think we need to do more in the UK about teaching about empire and the atrocities the UK committed, about the slave trade etc. I am also all for including non-european history, philosophy etc on curriculums and totally up for literature by more diverse authors being included in reading lists. While I read that race report commissioned by the tories with an open mind, I was not impressed by the fact that the authors seemed to think that what was needed was a patriotic education telling positive stories. Sometimes the most patriotic thing to do is to be able to own up to past mistakes. Germany teaches the third reich and the holocaust, why should we avoid learning about things like the Amritsar massacre?
