These people thing changing the code of our institutions works, specifically by giving them more power, that we can rid our institutions of the worst aspects of human nature: racism, sexism, xenophobia.
We can and should combat those aspects for sure, but we are also giving into another aspect of human nature: unchecked power and control, which will almost certainly lead to abuse. There is also no evidence that this will improve diversity.
It's just to make people feel good and put a few radicals in charge who want to dictate everything.
