You only fail to recognize this because their psychotic policies haven't yet been implemented.

Sorry for a reddity “ackshually this is a logical fallacy” but this is exemplary of begging the question: posing a question, then “proving” it to be true by tacit assumption that it is true. They set out to prove that socialists are worse than fascists. Because, ostensibly, socialism has never been tried, they then assume that it would be worse, lacking any evidence and relying on supposed common sense. The argument reduces to: socialism is worse than fascism because it is assumed to be so.
