There is a tradition of trivialisation of the extreme right-wing by right-wing conservative political majorities not only in Germany. And without political tailwind it is very difficult to face the problem.
When politicians here speak of the far right-wing as smaller, manageable groups, it may be true for the driving force or the organisers, but it completely understimates the movement (movement/'Bewegung' is b.t.w. pure Goebbels Nazi jargon) character of what has just happened in Chemnitz.
The connection of the right-wing extremists to a part of society where racist and anti-Semitic attitudes have always fermented has been getting closer, and is now breaking out. This has been formed politically, has become eligible in a way and is now out on the road.
The distance of 'normal people' to the extreme right-wing hardcore groups has been lost.
This movement in Saxony is being denied up to the political top of the Saxon state government to this day. The analysis of Germany's situation is thus wrong, and we will have more and more of what has happened in Chemnitz
