I was recently talking with a Russian friend of mine, and he told me that Finland is actually Slavic. His reasoning was that Russia and Finland share a long border and a lot of history
Please don’t burn me at the stake I’m just the messenger D:
I know next to nothing about this and just wanted to see if there was any truth to what he said from a cultural or historical standpoint


Sharing a border is no condition. Austria and Hungary where once a state, however Hungarians are not Germanic (The stuff about Austrian identity, Austrians as ethnic group and so on is actually rather new and I am way not an expert). Funny enough both differ in the language the same way as Finland and Russia.
