The article states that the Slovakian government, with this guy's support, is moving to take control of the media and the former president was being inundated with death threats. Ergo, a fascist by definition.
I don't want the US funding the Ukraine war either, but calling this guy a 'skeptic' or a 'populist' and not a fascist, as he clearly appears to be, is pretty shitty reporting, I think.
Someone who knows more please feel free to correct me if I'm misunderstanding something here.
