The kinds of people who have historically gotten screwed by biases come from every religion, ethnic group and culture in the world. Any genuine discussion would have to acknowledge that as a prerequisite. The narrative of oppressor and oppressed falls apart against the backdrop of reality when peoples real culture and history's are discussed. So does any potential political and economic power that can be gained through black and white grievance politics.
American Identity politics is about erasing peoples identities and histories and putting them into segregated groups based exclusively on skin color and gender then assigning a sliding scale between oppressor and oppressed to these groups. With 'white people' and 'male' being the oppressor and the other groups falling into some victim grievance class hierarchy who demand but will never get 'justice'. Its the perfect war of all against all that can be carefully manipulated by media and distract the population away from serious political and policy failures that we see all around us.
Identity Politics in the tech industry is simply ridding this wave trying to extract whatever power and resources it can before they become an inconvenience and money sink to corporations who think thy can use idpol for there own nefarious objectives.
I will point you to Charles H Smith who wrote an interesting essay on idpol from a leftist point of view.
Identity Politics = Totalitarianism
"The truth is we have more in common with people of different ethnicities and religions than we can possibly know in a totalitarian system drenched in the divisive propaganda of identity politics.
Identity politics are the core of every totalitarian state. Identity politics were the beating heart of Nazism, and the core strategy of the USSR's liquidation of kulaks and other groups identified as enemies of the state."
