Well I never think of politics as a straight line and there are positions taken by some now that would have been considered normal a few decades ago that are considered by the media as extreme now. Look at the Dems.
I did read the Guardian article on the German results yesterday, well one of them, now my Grandfather was Working Class, Union, long term Labour member, what was then considered left. So they interviewed someone in Germany who they consider left, well Progressive, not the same thing at all. Nothing much in common.
Anyway the last bit was going on about extreme views and how AfD's success is worrying but the good news is that Linke? which they described as an extreme Left party did well. Hello if you are against extreme, their word, parties how does this work out.
