That's enough to qualify someone as such. He is also a German citizen, he is free to claim both/either as he chooses but it's also not wrong for someone to call someone born in a country as being from that country. The wikipedia also cites the only reason they use "German" in his bio is because he responded on Reddit saying he was a naturalized German citizen. Nothing about a demand to exclusively wanting to be referenced as German.
Which by the way, his answer about being a German citizen was because people were attacking him for being born in Russia and claiming Mastodon was Russian spy tools and nonsense like that.
It would only be interesting if the blog writer was asked by Eugen Rochko to replace it with the nationality he prefers to claim, and refuses to do that.
It's only been a very recent move in social history to question this and instead ask why aren't we placing more importance on their environmental upbringing.
So, yes, it is interesting that the blog author went this way and isn't doing it with the usual purpose. I don't know why this bothers you so much, but this thread has gotten tiresome.
I am not bothered, and this thread is not tiresome. I am discussing why you feel the need to find this interesting, you brought it up. Blaming me for your stubbornness exhausting you will always render fruitless.
As an example, Elon Musk was born in Pretoria, South Africa. How many people think of him as South African? He has American, Canadian and South African citizenships. Is he Canadian?
It's considered malicious to call a trans person by their birth name, but if someone decides to leave their place of birth and publicly claim a different nationality that doesn't mean anything?
Another part of the identity equation people are questioning are things like pride, where we claim people as [group] because it makes us feel better (even if the individual does not claim that identity, whether it be the school they attended or where they were born, etc).
It's a lot of good discussion, but I feel due to political circumstances recently a lot of people have become very antagonistic towards Russian labels even if the individual themselves distances from the Russian administration, in the same way you can still be American if you hate the Biden administration.
