I always wondered why we didn't see the term crypto-fascism come up more in the last few years. Perhaps because it is too honest and gives room for manoeuvre (although equally it is going to be hard to disprove). Hence people shouting 'Nazi' - which reminds me of kids calling the cops in the UK 'The Feds' - both of which sound idiotic. We had the terms we needed (Neo-Nazi and Crypto-Fascist) and they both meant something.

I would say we also need to introduce a counterpart. e.g. crypto-stalinist or crypto-communist. As it is an equally plausible accusation to make that some people with hidden beliefs on that side of the spectrum could take them to those dark places.
