the meaning of symbols changes. the swastika used to mean something very different from what it means now. when someone wears a controversial symbol, they are opening up a conversation *today*, here and now, not in a previous time before the symbol gained whatever current notoriety it has.
if the iron cross is important to you (although why an anarchist would give a shit about military commendations is beyond me), then the work that would be appropriate is to reclaim it as a pre-fascist marker, not by wearing it (which is too ambiguous), but by educating people about its origins.
new age people have certainly made that effort re: the swastika. it hasn't gotten very far.
but if it is so important to you, then perhaps that is the most significant thing to be communicating to other people.
if other things you do are interesting, then maybe some people will look beyond the symbols. as lawrence says, you're choosing a difficult road.
this question certainly doesn't make a compelling argument for your anarchist beliefs, so perhaps you *are* actually more interested in social provocation?
