But in the end efficiency isn't my concern, as I have almost not visitors, what turns out to be more important is that Go has a lot of useful stuff in the standard library, especially the HTML templates, that allow me to write safe code easily. To test the statement, I'll even provide the link and invite anyone to try and break it: https://wwwcip.cs.fau.de/~oj14ozun/guestbook.cgi (the worst I anticipate happening is that someone could use up my storage quota, but even that should take a while).

I cannot claim that I understand it well, but my best guess is that these are images that represent a kind of culture that I have encountered both in real-life and online that I never felt comfortable around. It doesn't seem unreasonable that this uneasiness around people with identity-constituting interests in anime, Furries, MLP, medieval LARP, etc. transfers back onto their imagery. And to be clear, it is not like I inherently hate anime as a medium or the idea of anthropomorphism in art. There is some kind of social ineptitude around propagating these _kinds_ of interests that bugs me.
I cannot claim that I am satisfies with this explanation. I know that the dislike I feel for this is very similar to that I feel when visiting a hacker space where I don't know anyone. But I hope that I could at least give a feeling for why some people don't like seeing catgirls every time I open a repository and that it doesn't necessarily have anything to do with advocating for a "corporate soulless web".
