No, but like Nazis they are, shall we say prone to a certain class of delusion borne of over-rationalisation to the point that their expectations of what's best for the world and what is (more empirically, and thus harder) actually best for the world diverge dramatically.

In all cases there's a certain kind of lazy theology at play, in that all you need is a simple kernal of an idea and the details will look after themselves, to whit:

- Libertarianism: Everyone look after themselves and we'll be okay.

- Naziism: Lets just look after ourselves and we'll be okay.

- Fascism: Lets put the weak in their place and we'll be okay.

- Bolshevism: Let's just make sure everyone has the same stuff and we'll be okay.

Each and every one notwithstanding the fact that reality is always for more nuanced.
