I quickly looked in Google Scholar and found this paper titled "Pale and Geeky: Prevailing Stereotypes of Anime Fans", and I quote:
> The social distance items suggest that anime fans are indeed stigmatized. For example, non-fans indicated a willingness to interact with anime fans at a distance (e.g., neighbor, coworker), but did not wish for an anime fan to hold political power (e.g., governor) or be allowed into one’s personal life (e.g., relationship partner, roommate).

> We examined the content of anime fan stereotypes in a sample of non-fans (N = 146). Self-identified non-fans of anime wrote about a prototypical anime fan and rated the prototype’s personality their desired social distance from the prototype.
I think we can both see where conclusions drawn here might fail. Replace any human characteristic and have non-fans of that characteristic respond, and you’re likely to get similar results.
If you already see the person in front of you is not a pasty white nerd the statement doesn’t make as much of sn impression.
In which case the problem is really being a pasty white nerd.
I think the people the non-fans are probably thinking of are more likely "weeaboos", or people who are so obsessed with Japanese culture that they completely reject their own (the ones in really cringey videos). However, there are so many more people now that are either more open to the medium or just openly enjoy it but aren't really as visible - I'd love to see a reproduction of this test with this distinguishing factor.
