Um, no, because white males (of which Trump is a specimen) have not traditionally been stereotyped as having low IQs--on the contrary.
And because of that we must pretend that all black people are smart or else we are racist?
That's some major league bullshit. And the kind of bullshit double standards that is keeping race relations from progressing for decades. Until it is equally acceptable to call Maxine Waters and Louis Gohmert (for example) "low iq", we have a long way to go.
One way in which racism manifests itself the support and perpetuation of stereotypes. Perhaps you need to try to understand the history of racialized pseudo-scientific assertions about IQs.
Yes, these stereotypes exist. But the solution is not a knee-jerk rejection of any suggestion that any black person might not be highly intelligent.
