Progressive, and Conservative are all nouns.
Not in the context in which we're discussing, they're not.
- The Liberal Party of Canada (not "The Party of Liberals")
- The Conservative Party of Canada (not "The Party of Conservatives")
- The New Democratic Party of Canada (not "The Party of New Democrats")
and then back in the early 90's,
- The Progressive Conservative Party of Canada (not "The Party of Progressive Conservatives"...which, FYI...THAT would be the oxymoron by definition that you are trying to argue.)
In the context of party names, which is precisely what we are discussing, these words are adjectives.
Which brings me all the way back around to "The Socially Progressive Fiscally Conservative Party of Canada" being too long to fit on a sign, and so it's shortened to just Progressive Conservative. Which YOU seem to think means that Progressive is being used as an adjective for Conservative, which yes...WOULD be an oxymoron if that was how the words were used in the party name.
But...they're....not.... They are two adjectives describing two separate things (Fiscal policy & social policy)
You want to talk about English competency? How is the difference between adjective and noun and when to use each so difficult for you to grasp?
Good lord. I'm done. I tried being respectful, but you're beyond hopeless.
