So I do not see the solution in fighting populist rhetoric, but in adressing the cause of the fear of the people.
If you address it they won't have a reason to vote for you next time. This problem plagues many US cities.
This is precisely where I claim you've gone wrong.
> NGOs
NGOs are not democratic institutions per se. NGOs can be incredibly detrimental to societies, whether intentionally or through incompetence, and can be used by billionaires to social engineer societies as they see fit.
> the media
The media are not democratic institutions per se, even if they can in principle be used to communicate information needed to make sound political decisions. In practice, they've owned by someone with a view that's inseparable from the writing. So far I've seen corporate media banned and very often, in that part of the world, the corporate media are owned by powerful foreign interests, thus often becoming instruments for social engineering and propaganda.
> academia
A healthy academia can, again and in principle, be very important for the maintenance of an informed society, but here, too, they are not democratic institutions per se, and they have demonstrated enormous susceptibility to ideology (which is quite a charitable claim; they are, in fact, the breeding grounds of many of the ideologies that later enter the political sphere). Through funding (gov't and private foundations often backed by billionaires) and biased hiring, ideologues can be promoted and concentrated within the ranks of the university.
So I have to say I am a bit frustrated by the pervasive myopia about the reality of these kinds of political issues. What I see is often a credulous attitude toward the false narratives that corporate media have published.
Whether Orban is using appropriate means to achieve certain ends is the subject of another discussion, but that Hungary and other countries are the subject of foreign imperialist ideological bullying is not an open question as far as I am concerned. Whatever flaws Orban might have, realistically, I do not see any other forces that can mount a serious enough defense against these threats. (Mass immigration is only one thing Orban takes issue with, btw.)
It is also very ironic that in Hungary these independent (i.e. from state) institutions are replaced with ones who's mandate last longer than 2 terms of election - fairly obvious that public control is not the goal, but the exact opposite.
When one calls these institutions Democratic it's because they do represent opposition and thus a control mechanism. This does not mean that they're infallible or act for the good of society by definition but if they do not exist the government operates - de facto - in a completely uncontrolled framework. Unsurprisingly this is why many governments do try to dismantle these institutions in the first place.
>[..] but that Hungary and other countries are the subject of foreign imperialist ideological bullying is not an open question as far as I am concerned.
I agree that this is worthy of a discussion however I don't think this is the topic in question at all.
What is it that makes non-government organizations so democratic? Do they let the general public vote for their leaders?
I think you're being willfully naive here, I'm afraid.
I'm not going to go into the topic of migration and the "legality" of it. But the reason Orban is considered "radical" by many is not because of his stance on immigration first and foremost but because he's been dismantling democratic institutions left and right, starting with NGOs, the media, academia and to some extend even the judiciary. The fact that his rhetoric is hung up on blaming everything on George Soros does also not help.
