Since Australia banned the swastika and roman salute, its time we also ban the communist "hammer and sickle" and "communist fist gesture". 

Considering communism has lead directly to the deaths of over 100million people worldwide, and Australia has fought multiple wars against communist nations, we should not tolerate their symbols or flags being shown in public, nor the communist fist hand gesture. These are tools used for recruitment and intimidation purposes by communists the world over. Australia already banned symbols and flags of the far right, so now we need some balance and should do the same to the far left. 

Refusal to do so is basically signalling to the Australian people that we are infact ruled by communist sympathizers.
