DECOLONISE THE WORLD - NOT A TERRIBLE IDEA - JUST BEING PRESENTED BADLY?

The current decolonisation of westernised ideology that's doing the rounds in South Africa and which is being ridiculed brutally (oftentimes understandably given the idiotic ranting that we see on social media and newswires) - is it such a radical and stupid concept in reality?
We must presuppose that the world in which we live is on the pinnacle of success and balance as driven by westernised culture and if that were the case then all well and good - no argument.
But it isn't. It's anything but and I can't believe there's anyone among us that would assert we've created a workable model across the board.
It's broken.
The decolonise concept is, for me at least, actually quite simple but is being perverted fad-like by those who seek to use this mantle for other agendas and/or those who misrepresent the ideology through ignorance.
The problems that westernised thinking and culture have manifested (and we must admit there are plenty especially through its colonisation model of "civilisation") have resulted in a polarised world that's poised on the brink of self destruction if we aren't very careful.
It's also pretty much been a my way or the highway state of governance and indoctrination that's been imposed from the get go.
I think any rationally minded person would admit that we currently exist in an unsustainable world model that's run by people we both distrust and despise within governments that feel exclusive and dictatorial regardless of this illusory concept of democracy which has been failing for a very long time.
It's paradoxically exploitative and perhaps that's being realised fundamentally by black people even though the present government claims to represent them despite being within this westernised construct.
The problem with all of these worldview models is that they tend to be exclusive and comparative and dismissive of any thinking or modality that doesn't fit the prescribed worldview. And they all rely on the premise that the majority are right and dissenters are fools, however, history repeatedly shows us that the Mavericks change the world not the majority despite the freethinkers being subjected to mass peer ridicule so much of the time.
Materialist science is a great example of this - it shapes everything in our current reality as it's the accepted norm even when much of this thinking is based on ideas and "laws" that emanated from the 16th and 17th centuries and aren't questioned especially by scientists when much of that thinking is merely a perpetuation of dogma and doesn't stand up to any real form of scientific scrutiny. The establishment is unyielding and the dogma is enforced almost militantly.
Check out Rupert Sheldrake's work in this regard - a scientist who continues to question everything.
I'm all for a return to traditional ways and values that engenders inclusivity and an unbiased evaluation of the plethora of cultures that make up the whole. The sum may be greater than the parts but every part is vital to the whole.
That isn't what the contemporary or legacy driven westernised worldview has created or perpetuates.
I agree. It needs to change but not to supplant one set of imposed dogmas for another.
