As a violent faceless mennace existing in their streets, wanting to burn their buisnesses down and have the purge yeah its much more difficult to use the Bolshevik or COMMIES scare that effectively cause historicaly post ww2 that kind of scare was a narrative about the foreign other that has secret agents everywhere and anyone can be a secret commie, about the reds that make these secretive and villainous grand plans to undermine american values and way of life and take over. Would be innefficient to try and spin those sentiments and buzzwords into THE COMMIES being the "chaotic" face covered antifa blm teens. At most in the narrative "the reds" would be the ones that finance and are responsible behind the scenes for civil rights and anti war movements to spread chaos and instability in america (and at that point you actualy saw the red scare mindset being exploited very much so as "chinese/russians" are behind blm and everything , every chinese in the US being a CPC agent ,covid bioweapon and vuvuzela and cuba being sponsors of terrorism and a threat to murika).
