@Doobah47,
"If party politics constitutes a system of demagogue, then does that render a large portion of Western liberal 'democracy' a Fascist demagogue?" (Doobah47)
I think that depends largely on our working definition of "fascism."
People nowadays all too commonly use the term as a rather unconsidered, pejorative catch-all for anything deemed oppressive.
There are different types of fascism, and the subject goes deeper than face-value politics.
Will you please be more specific as to which "portion of Western liberal 'democracy' you are referring? Only by identifying this portion's attributes, their ideology and implementation of authority, can we begin to address your question on any meaningful level.
