RE: Commonality of Fictionkin from Anime?
I guess it depends on where you spend time, and what kind of spaces you're looking into.
One has to take into consideration that "anime" encompasses the entirety of Japanese animation- adult, and child oriented alike. You're lumping thousands of pieces of media into the same category, so naturally, you're going to see loads of anime characters. Plus, people tend to lump manga characters into the "anime" category, which is unfair, because "anime" literally means "animation". Manga is like the comic industry here- we don't conflate our comic and cartoon industries- as a matter of fact, comic geeks get extremely insulted when one does, and many adult animation fans really hate their material being referred to as "cartoons" as well.
Anyway, I can't really relate to your personal experiences, as I've been spending time in many multiple-oriented spaces, and a lot of the fictional identities present in those communities span the entire gamut. I'm also a part of kin communities on a broad range of platforms as well, and again, I see common cartoon and real life factives. Also I've met someone in the past who identified as Stephen Hawking.
It depends on the level of personal connection that's innately built into the character or individual. Albert Einstein, though inspirational, is a very, very cold and distant figure. Senkuu Ishigami from Dr. Stone, who is heavily inspired by Albert Einstein, however, is personified through the course of the anime and manga he's from to be extremely likeable, friendly, kind and determined. He has a personality you can really see, reflect off of, and relate to. Thus, it's way, way easier to form any kind of identity link than it is with a cold and distant historical figure.
Using one of my own fictional introjects as an example. :-P We have many, and though we personally have quite a few from anime and manga sources, I don't think that really accounts for much. We also have a factual introject of a real life person that i've never seen a double of. Lol. It really just depends.
