There is one school of thought (which the GFA falls under) which is what’s happened in the past is legitimate and we have to work from where we are and there is another which is that the colonial past is illegitimate and therefore any gains are also illegitimate and most be returned to their rightful owner.
I don’t subscribe to either necessarily but seeing as continuing prevailing attitudes among the colonial elite haven’t changed one bit I think we have no choice but to confront them gloves off style. It’s literally stealing our collective global future.
