You're pointing to a really important point, and Mr. Pankowski was absolutely right in that this is anti-Semitism in countries without Jews, and Islamophobia in countries with no Muslims.
By the way, that is why the fact that it's taking place in the unreal world of the Internet is also so important. This is about creating fictitious threats to the nation, and then the creation of parties who can save the nation from that threat. It's a type of psychological drama: “We can protect the nation; we will say that we will keep it pure and we will keep it clean.”
Then, of course, when they come into power, they make that argument even more forcefully: “We're here protecting the nation; therefore, we can be corrupt and we can steal, because only we can ensure that you are safe.”
It's playing on people's fears about safety or about continued prosperity, and with the fact that they're now part of a global economy and really part of a global information system, people see and hear or perceive many more threats than they would if they were just walking down the street.
It is a way of psychologically running and winning elections.
