Svalbard, Norway doesn't even require a visa to live there, but you do need to be able to support yourself (basically, have a job lined up before you arrive) and you'll need to be able to enter the Schengen region to get there.

Not sure why you'd want to go out of your way to immigrate to Russia of all places given... Gestures at Putin

As a Russian: Russia is not open-minded at all, where did you get that idea? Same as in the US, there is a part of population that doesn't know/understand shit about diversity, human rights, etc, but will be eager to tell you that you are not like them (and also live wrong, dress wrong, etc)

It depends on the color of your skin and where you're from, what you bring to the country, etc.

Haven't been there, but on accounts of some friends, and a YouTuber who travelled across South America back and forth, Colombia and Brazil could be good choices. SA cultures look generally warmer and more social. I don't know about the details, but maybe there's someone here who could comment on that (and I'm ok with being completely wrong about everything:) )

Germany: Berlin (such as any other capital city full of immigrants) would be a good choice. Germans are not the best in accepting foreigners as equals, but your freedoms will be protected by laws, and there are so many different sorts of people that you won't look strange, whoever you are

Ultimately probably comes down to which countries culture you'd assimilate best into

I heard Latvia is really safe. Maybe Kyrgyzstan too but I can't say, all I know is that a girl who bullied my girlfriend was born there but can't say about the people there...

Germany, especially cities like Berlin, is full of immigrants, no?
