It's also very strange to think that team members should be responsible for speaking for their race. Imagine if your team had a black engineer and your team expected him to explain to everyone "the black perspective" or "how will black people think about this". An individual doesn't represent anyone beyond themselves and, ironically, it is racist to think otherwise. A black engineer is there to do the job of an engineer, not tell you what his racial group will think. If you want to know what a demographic will think of something you use surveys, focus groups, and market research - DEI is not relevant.
