Does a tin foil hat provide any form of protection against this?
It is not a conspiracy theory, it is just a consequence of their actions.
They believe, like the worker movement in 1918 in Finland believed, that Finland is doomed unless it merges with a larger union. They aren't evil, or conspiring; just ignorant and wrong. They genuinely believe that unless they replace Finns with humanitarian immigrants, something bad will happen to everyone; that it must be done for the world to be safe. Sometimes that bad thing is genetics ("we need better genes", even though most humanitarian immigrants suffer from
consanguinity more than Finns), sometimes it is the aging population ("we need someone to wipe our bums when we are old", even though employment rate among the immigrants is significantly lower than average, and raw numbers indicate each humanitarian immigrants is financially a negative net loss on average for the society), sometimes it is "white man's burden" (the tar in most slave ships was produced in Finland), sometimes international obligations, sometimes something else.
Did you know that Finns are basically what remains of the hunter-gather population all over Europe, up till agriculture came along? (See e.g.
this, a report by Swedish archaeologists, using bog corpses dating back 5000 years.) No, neither do Finns. We are still taught in school that we displaced Sami people, coming from a bend somewhere in the river Volga. And that we should be ashamed for our history. Being a proud Finn is worse than announcing oneself as a reborn Adolf Hitler. Try waving a Finnish flag on a sunny non-national holiday, and you will be spat on.
Fifteen years ago, at Helsinki University, I took the mandatory Swedish class. The lecturer asked the students how they identify themselves: as Helsinki'ers, as Finns, or as Europeans. 95% of the students -- everyone except me -- said they identify themselves primarily as Helsinki'er, then as an European, and laughed the idea of identifying as a Finn. That is how deeply self-loathing is ingrained in current youth. (Me, I'm a barrel-raised woodland creature, and as basic [in the derogatory sense] a finn as you can get.)
Everything I am saying here is easily verifiable. I am not implying that there is someone wringing their hands together, cackling evilly, with a plan on how to replace the population in Finland with immigrants. I am just saying that the current actions inevitably lead to that.
The most important of those actions, in the current pandemic, and pertinent to this thread, is their absolute refusal to even consider reinstating border controls.
The reason for that is that while the majority of Finns have clamored for border controls ever since 2015, and returning humanitarian immigrants to the safe EU countries they came from, our government has categorically stated it is impossible: they are bound by law to not do that, that they do not have the legal right to reinstate border controls.
If they now reinstated border controls, even for curbing the spread of the pandemic, they would immediately prove they have lied to Finnish citizens for years.
So, instead of doing the sane thing and protect everyone living in Finland by instating health inspection based border controls,
our beloved leaders are still claiming it would be illegal for them to do so.
The only reason to do so, is 1) to avoid being exposed as a liar, and 2) to avoid risking their long-term desire, of Finland being a haven for humanitarian immigration.
This is not a conspiracy theory, or any theory at all, because the first reason is a consequence of the second, and there are no other reasons stated by our politicians in the media (or even in private).
