“Back” pride or “white” pride are both idiotic.
The former is an euphemism for “descendents of African slaves” pride.
Recent migrants from Africa share little to jo culture eith those who are slave descendents. A first or second generation Tanzanian immigrant is higher educated, better paid, more law abiding, more likely to have intact families and a strong family culture.
And “white” pride is completely idiotic.
You can be proud to be English or Swedish or Catalan or Albanian, but “white” is not and never has been a single cultural entity
