There are no extreme forms of DEI because DEI is just making sure that everyone is able to be included and to discourage discrimination.

An all black college for example is not DEI. It is trying to counter systemic racism by providing opportunities to those that have historically and currently been excluded, so the goals are the same but it isn't DEI.

So, there's no countries of majority black people on Earth? Don't you mean a majority black college in the USA? But wouldn't that majority by definition exclude other minorities like east asians, south asians, native americans, Hispanics et al? And what is a white person? A person from the south of Spain is indistinguishable from a person from North Africa, yet both originate from completely different backgrounds and neither would be white passing in the US. What about poor white people, do JayZ's children deserve a pass because they are black but the children of a Ukrainian migrant do not because they are technically white even if they are from a refugee family with little financial means?

What you said is myopic, nonsensical and a perfect example of an oxymoron, I'm going to go on a limb and guess you're US american. Congrats, it's regardation like the one you spouted that got Trump elected.
