I believe their argument is that there is no coherent, practical position that can be described as decolonization in this modern sense. Both the dictionary and wikipedia only define decolonization in a conventional, imperial power withdrawing sense.

Absent there being any clear definition of the concept I am not sure the onus is on OP to define it.
