I am not ‘TLightful’, but I’m guessing it’s because you used the term “The Elect”, which only certain groups use. It’s one of the shibboleths of these modern times.
The groups agreeing with that author, basically. The author is black, yes, but he also (according to Wikipedia) criticizes a number of left-wing and activist educators, the anti-racism movement, the concept of “microaggressions” and has denounced affirmative action based on race. So he is, understandably, not without controversy and detractors. Coming back to the term “The Elect”, it is a term adopted by him to make a political point. Therefore, only people who agree with that point will use the term, and people who disagree with that point (or with him, more broadly) will take affront to the term, as is the custom of these modern times.
