I think the key term here is "dictatorship". There's been capitalist dictatorships as well, and they've been terrible (Franco in Spain comes to mind for example).

I wouldn't be worried by the modern rejection of capitalism, because it's definitely not a rejection of democratic systems. In fact, if anything, it's fueled by the failure of democracy in the face of the inevitable oligarchy product of capitalist economics. If anything, I see this as a wave of people trying to save democracy.
