Yes, but he’s applying the inverse here: asking me to assume that a non-Black coded name doesn’t refer to a Black person. That rests on the stereotype that most Black people have Black-coded names.
As someone who belongs to a Muslim family living in this country since the 1920s, I for once have to drop my jaw, side with rayiner and point out that you’re being the tendentious one (many such names like Jamal are in fact held by “whites” and non Blacks too)
