This is very true. In Belgium Vlaams Belang (extreme right-wing) has recently written an immegration memo and it's supposed to be very moderate/reasonable given their views. When asked about how their voters would react to such a "lame duck memo", and the response of one of the others in the studio was literally "as if their voters are reading what they put in their policy notes". And that's true. I don't think (or don't want to think) that most people who voted PVV are racists are fine with racism, but I see it more as a vote against the political establishment because they are fed up with the way things are going and how their "daily lives concerns" are not heard/dealt with by politicians. And then you get this situation where they're just like "let's see how this other guy does then".
His policy will need to be within EU / human rights guidelines but even then you can do a lot of damage towards previously acquired rights for some groups of the population.
It's the worst form of government except for all others
I fear for my country next year, even while I perfectly fit the description of what right-wing would describe as an ideal citizen in their backwards views.
