I'm not necessarily referring to fringe organisations.
The best example of this that I can think of is the recent Die Linke electoral victory in Berlin. They have the same policy on European security as AfD.
It's a clear example of Horseshoe Theory. Pseudo-intellectuals in Germany may argue that the position is not the same because the motivations are not the same, but if you're sitting in Ukraine, feeling the walls shake, and seeing your pets tremble in terror, you really couldn't give a shit what some leftie in Germany thinks — the result is the same as the openly pro-Kremlin German far-right.
