> Throughout my childhood, I always thought Black people seemed so cool and funny. They exude confidence and it intimidated my to make friends with them.

Speaking as black person this is an astute observation which I have observed. In Africa sometimes this is due to English not being someone's first language. In a meeting with people from different races I have noticed my black colleagues are way less vocal than when we are talking in Zulu on our own. They have a different demeanor and come out as more forceful and confident in Zulu. In English meeting they are less forceful.
