You can’t blame Obama! Not for anything that is currently go wrong in or for America or in the world at large. This is not to say that boy isn’t culpable for these; it’s just that is wrong for Americans to judge him for these things.
An American has to remember the weight of history attached to holding Blacks accountable for their actions and inactions and how society’s previously have done so has disproportionately negatively impacted Blacks’ social and economic outcomes.
You can’t blame Obama even though you could and would blame a White POTUS for exactly the same things in exactly the same circumstances because it’s racist to hold a Black to the same standards of behavior and performance as a White.
