If that is what you're saying, then I think it's supportable and also that "decolonization" is an unfortunate choice of terminology because it is loaded with connotation and non-neutrality. Language matters, and choosing non-alienating language makes it more inclusive to more participants (including western civ folks).
More rigor, better scholarship, incorporation of more diverse views are all things people can get behind. If the system is open to disputation, feedback, analysis, etc. while pursuing the widest possible range of views out there from under-represented voices, then great. I also want to add that this is also the default mode in academia especially at freer places like the University of Chicago.
If it means preventing disputation on the basis of a person's identity/affiliations, disavowing empiricism and heavily favoring narrative untethered to basic standards of evidence, inserting overt agenda into what ought to be neutral arms-length investigations, then I find myself opposing the approach in the strongest possible terms and will actively work to decenter and dismantle such efforts. This latter approach debases scholarship and amplifies poorly-defended ideas as the norm.
I've seen both approaches but in the academy right now, I see the latter approach being centered, to the detriment of the mission of academia.
