Say aorto, what you ask for is a term to describe a cultural process that has maybe a semantical political function, but not a proved function in fact.

Hypothetically, perhaps such a word would be useful, but I doubt it.

With today's consensus understanding of the nature of madkind's ever-changing culture, such a process has no standing in the cognitive thoughts of those who think deeply of such matters , so, unless you yourself can demonstrate the reality of the transformation that you wish to name, your new name will quickly be rendered clutter; but if you can make your point, then you can certainly name it as you please and all will be happy.

So if you please, please make your point about MacDonaldism.
