You, like, don’t? You use existing go-to terms.
I was misunderstood for I find this exact wording cringe for far-left is an invention of rightwing propaganda and in itself denies description. Hence the question.
The salient point is that we don’t try to hide or disguise what we actually believe
It is a topic of it’s own discussion (and in r/anarchism and other spaces it was), but with how anarchy is coupled with disaster in a state-provided vocabular, many call themselves libsoc for example, e.g. I default to socialism or socdem. It is, by some degree, muddies the water, at least for those who don’t know these things intersect with big scary words.
The difference is, probably, more nuanced. Although both are kinda off-color in a public discussion, fascism unlike anrachism is about statism, nepotism, populism, exclusion, big capital and they hide that because otherwise their goals put clear would frighten off regular folks (and not the state and capital). Anarchism isn’t spoken directly because it’s the state’s dogma that scares people, while the causes are not even close but common and even though about by them already.
I call myself libsoc to randos, but I’ll gladly call myself anarchist as well if I know they’re not afraid of the word. Reactionaries however will bend themselves backwards to pass as centrists or “concerned citizens”. They will of course go all “the time for talking is past” when cornered.
