Arguably it was used often as one around the time of its inception.  A lot of Communists back then threw the word out to slander dissidents.  Hell, Orwell's semi-red pill on socialism happened when the volunteer soldiers he joined going to the Spanish Civil War got called fascists because of the Communist infighting going on if memory serves me well enough.

Well, and also that they were rounded up and killed.

There were Communists and anarchists against the actual fascists, and the Communists killed the anarchists in order to ensure they would control the government in the event that their alliance defeated the fascists. 

Then the Communists lost pretty conclusively. 

Communists use the same playbook every time.
