“Who controls the past controls the future. Who controls the present controls the past.” George Orwell
Your culture is your historical values. That is the reason it is very important to tell your own story. Other people cannot tell your story without missing something very important. For an example, we Africans speak with our whole body, that’s the power of expression and it gives meaning to the words being spoken. Meanwhile, another culture considers that excited expression as aggressiveness. Now, what do you think if someone from that other culture is given the duty to tell the story of Africans? This applies to other cultures too.
Every culture undergoes evolution and the positive evolution of a culture is for the evolution to take place within the values of that culture. That is the progressive way for a culture to deal with its past no matter how crude or cruel it was and not by attempting to force the values of another culture (which had obviously gone through its own evolution within its cultural values) into your own.
Your past is an investment and if you handle it well today (rather than denying or running away from it), a brighter future is ahead of you.
African parents in diaspora are unfortunately failing in this regard.
