@Anarkat @schratze Etymologically, what makes both "sir" or "madam" honorifics is that they both express deference in a hierarchy to the addressed person. Sir -> sire -> senior from Latin senilis "of old age", and madame -> ma dame -> mea domina from Latin domina "of the house".
So I can see the suggestion of "comrade" breaks out of both the gender-binary AND the hierarchical deference implied in these words.
A bunch of technomancers in the fediverse. Keep it fairly clean please. This arcology is for all who wash up upon it's digital shore.
