i use the term anarchist because it's how i organize, the people i organize with, and the values i hold.
i picked .ml at the time because it was the developer instance, but i've stuck with it because it pisses people off.
i haven't found places like hexbear to be unwelcoming either; the comm i mod there even has an explicit rule against sectarianism (ie, if an ml is shittalking anarchists broadly it will get moderated). i don't have anything against db0, i even help mod a comm there too.
