Pushing back against ideas of critical race theory is important lest they dominate all our discourse and turn us all into victims.
(also note that "minoritized background" is a very broad descriptor; people who are the first in their family to go to university and have a white-collar job often experience the same problem of missing pieces of tacit knowledge and not knowing what they are expected to do)
This stuff is vulnerable to the "euphemism treadmill", where as soon as someone comes up with more "appropriate" language the same people get upset again because the actual real referent hasn't changed.
I'll admit it's kind of nit-picking. But someone did get the wrong idea from it.
