Hiring preferences for PoC is discriminating against all not PoC. It is in practice exactly what these initiatives claim to be fighting, bigotry.
No, DEI is about replacing one bias with another in order to make a bunch of white people feel better about themselves. DEI doesn't consider Indians or South Asian looking people "People of color", because there are "too many of them in tech already". DEI is just institutionalize racism. So much that some Indians have to fake being black to get jobs in DEI corporations, cause white people can't always tell the difference.
The baseline was never equality, however DEI is blatantly racist against people who objectively suffer from racial discrimination themselves.
From which perspective are race categorized in USA? From the white man's perspective. These DEI are all about some's ego and sense of guilt. Never about fairness nor equal opportunity. Yet these programs makes people who themselves are victim of racism, who never had anything to do with US slavery, pay the price individually, regardless of the inherited wealth/connections AKA socio-economic background.
Of course all I said is true, there is just the racism DEI corporations care about and the racism they don't care about, which is the direct result of DEI policies.
