A little history lesson: Many years ago, the Federal Government told its agencies and instrumentalities to avoid discrimination against, mainly, "Negros" and women (to comply with the 14th Amendment), there were few tangible, large scale improvements in the lot of these two groups. The Supreme Court suspected that intelligent bigots could "prove" they were not discriminating even though the result was that they were only hiring and promoting white males. So the USSC invented something called, "Affirmative Action," which - they thought - would force the Whites in power to hire and promote the groups which were the victims of insidious discrimination
But Affirmative Action had some constitutional problems of its own. Indeed, Affirmative Action is DISCRIMINATING against white males in favor of blacks and women, in the name of eliminating discrimination. The country was collectively pissed.
So the USSC invented the concept of "diversity." They said that discrimination in the name of Affirmative Action was still bad (and unconstitutional), but if an organization wanted to have policies that promoted "diversity" (doing the same thing as Affirmative Action, but denying it), that would be OK.
And that's where we are now. Colleges and state agencies and big companies all have "diversity" programs that are theoretically intended to diversify the workforce (bring in a "representative" number of several groups which are perceived to be the victims of discrimination) for their own betterment. Parenthetically one might mention that no one has ever documented how that "betterment" comes about or its tangible benefits, but I digress.
The OP implies that a "successful" program of promoting "diversity" does not really lead to "inclusion" because the beneficiaries of the Diversity programs have to "think white" and "act white" and "talk white" in order to be included. Thus, they must abandon the culture that would make the workplace "diverse" in order to get admitted, hired, or promoted.
I respectfully disagree. It is not "white" to speak proper English; it is American. It is not "white" to dress according to business norms, or be punctual, or be respectful of authority, or go about your daily tasks with enthusiasm and grace. These things are required of everyone, and many people have to abandon the language, dress, and culture of their home or neighborhood in order to be accepted in academe, the workplace, or society.
There is a five-letter word that describes those who feel strongly as the OP does: "loser."
