By all means, name an alternative cure that doesn't also butcher and imprison people under a repressive regime of some sort while denying even basic personal freedoms.
Or would you like to claim that a large part of Europe was "cured" of fascism after WWII by Stalin's USSR and its system, or that Nationalist China was cured of its (essentially) fascistic government by the liberating beauty of Maoism?
The socially democratic, largely western capitalist model of mostly free markets has indeed been fairly good at resisting the kind of extreme governments and despotic states that most of history endured. It's not perfect, and authoritarian regimes do develop capitalist economies, but compared to any alternative we've seen so far, it's a winner hands down.
Such an argument is far removed from any simplistic bullshit about deriding Americans for their cultural values (which happen to be essentially not bad despite the nose sniffing they get from so many people in so many countries with their own bloody, turbulent histories of despotic and revolutionary violence.) For example, given most of Europe's history well into the 20th century, it's laughable to see Europeans in particular feeling superior to Americans.
I'm not American, but rather born and raised in a scandinavian democratic socialist paradise. And while I see it could be lot worse and really not at all fascist, I think there are places where we should use the free market more, not less. It's the best protection against fascism.
Tell me you are American without telling me you are American!
