I certainly will not visit Greece any time soon (I have did it in the past).

Anecdotically, I have a cousin who has been living in Greece for at least 15 years. She is Caucasian and she speaks perfect Greek (as I noticed every time I have visited her in Greece... locals wouldn't even noticed she is a foreigner when she speaks - and we have nothing Greek in our family -). So you can tell she is perfectly integrated.

Anyway she has a small company and does businesses with a number of countries... among them Turkey. For some reason, those Golden Dawn people learnt about that (how?) and they made a call telling how wrong was to make business with such places... and she should stop (understand that in whatever way). Telling the police is gonna help because probably they don't care... and because many of those GD people are policemen themselves.

It is hard to believe this nazi-style prosecutions happen in Europe in the XXI century. And considering how the Greek society is so keen on Golden Dawn and their lack of self-criticism... I have very little sympathy for their situation.
