Can someone explain roots of what really is behind URM and diversity disease that is killing good old meritocracy, who and why is pushing it?
It goes straight against meritocracy. It is based on flawed root theory of giving a chance to all underrepresented groups and they will get equal in demonstrated merits. It even goes to the point of pushing deeply flawed slogans "we're all equal" by force and fear. It is sick and immoral as it almost all the times goes against the universal moral and right rule "equal criteria and rights to all". It would be fair and moral to try to address any difference in outcomes at the root, for example helping underrepresented groups to sign up to certain school degrees in higher numbers and or offer courses. It would be also more fair to apply rules equally to other professions, like the ones that have opposite distributions as basketball, nurses, truck drivers and on. But that is not happening, which in itself is revealing.
Is government imposing rules onto companies? (and then companies maybe see that they can not reason with government the only thing they can do to avoid penalties is to implement ill rules blindly)
Is it driven by HR reality detachment? (I read about number of scientific researches on discrimination and misrepresentation, but they were highly flawed and there are opposing research papers as well as prominent professors voicing how some of their work was misused. Are these HR people under delusions like communist or fascist like ideas)
