I can see where this thread is going already and I'm not too interested in following it through. I will say:
If it is a Nazi swastika than of course she realises its implications and offence. It is there to advertise her views, to exhibit her confidence in her beliefs, to gain support from the likeminded and to directly offend those who oppose it.
If she moves within fascist/alternative circles and participates in extreme art, music, performance, tattooing etc etc getting money/employment and peers is not hard at all.
It certainly looks like she succeeded in making an impression because the OP went home and started a thread on her, musing about who she is, her life, interests, thought processes, beliefs and here we all are talking about it. She has suceeded 100% in her aim to make an impression through the displaying of one symbol. One tiny symbol. One up for her.
