In the end, the KKK did not choose to support Donald Trump because he was a Republican but because they agreed with the ideas that he (and other far-right Republicans) spout. It is finally time to face the rise in the twenty-first century of a new form of white nationalism and its alignment with many leaders of the Republican Party, including Trump.
Hmmmm… I'd argue against them being communists, rather they are what I'd like to call "communist party buorgeoisie".
The North Korean System has much in common with fascism. But I don't know if I'd call them fascists.
For sure they are evil authoritarian goons, but fascism is more than that, because on top of being build on authoritarianism, nationalism, militarism and often racism, it is also expansionist, anti-liberal, anti-communist and anti-socialist, it is overwhelmingly corporatist, placed firmly in the spectrum of the right. And - in a surprising twist - anti-conservative in it's revolutionary mindset.
North Korea for one is clearly left-nationalist authoritarian. I'd even go so far as to call it a Stalinist system. It is anything but corporatist except where it is necessarily subservient to China.
China on the other hand has left its communist days behind and has become a major capitalist player on the world stage, creating an export-focused capitalist society with strong corporatist economy. And holy shit, if China isn't chauvinist expansionist I don't know who qualifies… So yes, they can likely be classified as fascists.
