You must have noticed the Hitler comparisons, right?

In human bodies, the first thing a virus targets is the immune system. As in human bodies, the first thing Dictatorships target is freedom of expression and more specifically, press freedom.

The notion of dictators as "criminals" is imprecise because, while their behavior might be considered criminal in the public court of opinion, they are technically "above the law" or, in another sense, they are synonymous with the law, since a dictator's will and the law of the land are, for all practical purposes, one and the same.
