That was true for the original founding of the parties but thats not why they keep growing. This is important to understand.

The parties are right wing and racist, they also gain votes from people who just want to be heard and think all other parties are too much like the current ones.

The anti-establishment sentiment is so bad that it also rewards whoever shouts the most outrageous things; if you call them out on it, you're obviously part of the establishment.

They are racist, and are being rewarded for racist statements (e.g. Wilders getting a crowd to shout "Fewer Moroccans! Fewer Moroccans!", or Trump's Mexican wall or keeping muslims out of the US).

You have nothing to back that claim up.

You are grouping a bunch of very different people into one group the very thing liberals are normally quick to react to when it's done by the right.

You are part of the very reason there even is a right wing.

But each to their own of course.

I'm convinced that a big reason for them to keep growing is that it gets more and more acceptable to provide simplistic and right wing answers to the problems.

You are wrong then and will continue to miss the most important thing. People are loosing their belief in the future and their ability for prospering and so they are simply looking for someone who take their concerns serious. The left used to do that.

Or if you insist on you own interpretation. You should instead ask yourself why more and more people buy into that view. The answer to neither of them are racism or fascism.

But the right doesn't take their concerns seriously, they offer no solutions whatsoever. They just shout outrageous, unrealistic oneliners.

The right exploits their concerns, which is easier to be perceived as addressing them when no one else is even acknowledging them.

Very well put.

The left ignores them completely. So they are grasping for every straw they can.

They offer the solution of stopping for the influx of immigration. One of the key issues many in europe see.

Just ask the unions. They are increasingly fighting against the cheaper labour in ex. construction undermining the salaries of their own national members.

The left have no response to that what so ever.

But immigration _isn't_ a key issue, it's not the cause of these peoples' troubles. They get told that, so that they can be provided with simplistic solutions.

Globalization is the problem, technology making jobs obsolete is the problem, natural limits to growth of world economy are the problem, climate change and energy crunch will be huge problems for them soon. But those are hard to explain and much harder to solve, so the idiots win.

Edit: Sorry, I read "refugees" when I saw you mention immigrants. Cheap labour from inside the EU is a real problem.

The right has one simply solution which actually in the short run is the most rational one.

Stop immigration.

I am sure calling someone an idiot just because they represent another view than you is under your own normal level too.

You aren't an idiot just because you are skeptic towards immigration. National Conservative is a totally fair position to take.

There is racism in some quarters, but there are also plenty of people who are just opposed to the free movement of people on selfish grounds.
