Antonio Gramsci.

Antonio who? You may not have heard of this Italian communist who died way back in 1937, but it is a name which would be immediately recognised by today's liberal elite as principal amongst their founding gurus.
Just as a trotskyite theme could be found running just below the surface of the revolutionary marxists of the working class who used to dominate all our trade unions - [now an endangered species, of course and apparently festering quietly in The Green Party] - Gramsci is one of the key founding fathers of the political philosophy which is currently wrecking the entire western world.
