So having an alter ego would be a fursona?

It's worth noting that Kimba's influence on The Lion King was marginal at best as outside of character species (which are limited to African species in both mediums) there are hardly any similarities.

Oh man do I have a YMS video for you

No, you're correct about weebs being obsessed with Japanese culture in general. Weebs do tend to be obsessed with Japanese culture, however it's like the difference between someone who has a degree in film history and a cinemaphile. Or a geek and someone who enjoys super hero movies.

Edit: or a tankie vs a communist or socialist

I don't know if there's a complete collection anywhere, but here's a Shincho Monthly article that has some of it (obviously NSFW): https://archive.org/details/erotica_of_osamu_tezuka

Most of it is transformation fetish stuff, ranging from human->anthro stuff to weirder inanimate and body-horror-esque/"what-has-science-done" kinda transformation art. Tbh I kinda wonder how much of it was really fetish fuel and how much of it was artistic musings. Some of the drawings are so bizarre that it's hard to believe that they'd actually trigger someone's fetish and seem more like he was just exploring surreal transformations.

Then again, I've been exposed to a lot of obviously pornographic art that normies would think was too weird to be fetish material, so I'm probably mistaken.

We're all furries on this blessed day.

No. Weebs are people who are fans of Japanese culture in general, usually to an extreme; ignoring shortcomings of Japanese culture and politics in favor of a highly romanticized version of Japan. An anime fan might think Japan is cool, a weeb thinks Japan is some kind of magical fairyland where catgirls grow on trees.

It's like tankies vs communists and socialists.
