The fact that far too many people cannot recognize fascism unless it looks exactly like Nazi Germany is very dangerous.
This is why Hitler purged the Brownshirts in 1934. They were radical revolutionaries at a time when he wanted to project an image of a respectable Germany, to keep big business on side.
@Strandjunker there is a specific definition of fascism.
For example in the UK, many on the left are crying "fascists". It is as inaccurate as it is unhelpful. Popularist, racist rhetoric is not fascism
