Yes, I agree that allying oneself with Farage and Trump makes you reactionary. I also conclude from the above that anyone who opposes "the west" is reactionary. For Cohen assumes that "the west" is progressive. I think not.
I think that Cohen is a defender of "the west", which means he allies himself with a history of state imperialism' crimes of western regimes: wars, invasions, plunder of public wealth, huge inequality, tacit backing of theocracies and dictatorships, enslavement through debt, harbouring of oligarchs, exploitation, instituional racism (especially in the US) ... What is Cohen's "west" if not that global capitalist system of domination? Does that make Cohen a progressive leftist?
