Leaving aside the absurd and juvenile "Nazi" slur ("fascist" is less of a stretch), I disagree with your analysis. I think it's exactly the opposite. I think it's because mainstream politicians have refused to address the reasonable aspects of people's concerns (about immigration, in particular), and because progressive activists have gone off the leash in their wild accusations of racism at the slightest contradiction of their opinions, that we've ended up in this situation of the far right getting into power all over the place.

Once again: I do not vote for these parties. Anyway, we are now completely offtopic so let's leave it there.

You say it like it's an insult! Actually I usually vote green. And in Europe the greens are really greens, rather than just spoilers who help Bushes and Trumps into power.
