Yea, its fukked up situation over there, I'm uregu from Morocco which is considered berber(hate the term) and we get alot hate from Arabs, Europeans, etc...
I give alot props to African Americans cause I truly didn't understand racism (primarily in regards to skin tone) till I moved to America
To make a long story short, even though alot people Mauritania would be considered black(even upper class) they won't understand it till they go Saudi, Egypt, or Levant, which is why they have alot fukked up beliefs.....
