Not only did Finland take part in the holocaust by exterminating the Roma living in Finland (or forcing them to fight in the nazi suicide squads), but Estonia also handed over Jews to the Gestapo.

Aside from that, officials confirmed a few years ago that the Finnish Waffen‐SS participated directly in Axis atrocities. While I personally wouldn’t classify 1940s Finland as a fascist state, I understand those who do and the politics that it adopted compel me to classify it as parafascist. An example from Finland’s Holocaust:

Before taking up positions of artistic and institutional leadership in Finland, [Arvi] Kivimaa had already been an established poet, essayist, and writer. […] The views Kivimaa absorbs into Eurooppalainen veljeskunta align with those expressed in a range of German‐language books sustained by the Finnish state—many written by academics who, like Kivimaa, resumed distinguished institutional careers after the war—identifying Finland within the rhetoric of Third Reich racial and expansionist ideologies for consumption by readers of both German and Finnish.

From Finland in World War II:

The widespread Finnish animosity towards the Russians was also more or less explicitly present in the studies on Greater Finland and the occupation of Eastern Karelia. In 1986 Heikki Luostarinen’s doctoral dissertation on the enemy image of Russians and the Soviet Union in the Finnish conservative and rightwing press during the Continuation War focused on the issue in detail and showed the deep racial hatred in the wartime media and mentality.

There is a lot more to be said about Finland, but to keep things short it is a gross oversimplification to summarise its alliance with the Third Reich as only ‘picking the lesser evil’.

Now, no offence, but I think that you’d be happier or healthier doing something else with your time than trying to reason with anticommunists, seeing as how they can just make up whatever stuff that they want while instantly throwing actual research into the trashcan. Are you sure that you don’t want to try something else? Exercising? Juggling? Reading more books? Even playing drunk lawn darts would be better.
