Simply, IMO, because we are still not really allowed to be seen as individuals.
I think that's one of the massive questions that have beset us as a race. If we assert individual identities, we're seen by some as abandoning the group identity. I don't believe that we're a monolith. There are just too many different types of AfAms in this country to agree on every single issue.
On the other hand, when some of us act crazy like Omarosa or Fiddy and G-Neck (Gorilla Unit

), we are all lumped into the looniness. That does annoy me, and I sometimes feel pressure that I have to be on point 24/7.
