Does it really matter?

Both fascism and communism appear when enough people are fed up. Really fed up.
So fed up that they have become gullible enough to accept the lies promised by those who want to get ‘at the top’, in the given circumstances.
The difference between fascism and communism, the only one, being the exact conditions which had caused the ire of the people.
Communism can, and will presently be, presented as the only possible alternative to those confronted by a ‘black ceiling’.
Fascism, on the other hand, can, and will presently be, presented as the only possible alternative to those confronted by a ‘glass ceiling’.
The always poor who have no chance of improving their lot will accept the lies promised by the communists. They don’t know any better so they believe those lies are possible.
The impoverished who have no chance of returning to their former situation will accept the lies professed by the fascists. They know what they have lost and need to find a culprit to blame for what had happened.

In a sense you can identify fascism with the right and communism with the left.
In reality, fascism and communism are the two ugly faces of the same fake coin.
