Stuyding logic 101. If (as you suggest) all muslims are black but we know not all blacks are muslims, then the racial status black IS irrelevant.
Apparently you haven't been doing very well in logic 101. On what planet do you reside? Are you aware of the Nation of Islam? Are you aware of the large number of black converts to Islam in our prisons?
Of course, not all Muslims in this country are black. But the vast majority of American converts to Islam are black. No matter how much you want to deny that, you're full of shit.
