At the risk of sounding like I'm telling people the "right" or "wrong" way to spread the message.... I think there can be a lot of value in abadoning the labels.
People will always have prejudices and hangups attached to labels. When they hear the word anarchy the might end up picturing roving gangs of murderous thugs a la Mad Max. There are probably less hangups with the term voluntaryism since it's less well known and sounds vaguely positive, but you never know what prejudices another person holds.
I like this idea of just telling people that I'm a "consistent human being." So thanks for that :)
