Why are you guys acting like this is a new phenomenon?? Asian music, drama & animation/manga have been a thing for a while now. I think the K-drama "Winter Sonata" from early 00s, was the one that popularized the Korean wave.
J-entertainment used to be very huge in the 90s to late 00s, but it died down thanks to the stingy Japanese. I used to know a lot of Somalis who were into Visual-kei lol
Kpop didn't kick off until DBSK/TVXQ(a boy group) took over all Asian music industries. They had the biggest impact in Japan, and even now 14 years later, they are still the "it" boyband. For those who are trashing Kpop and saying at least muh anime is better...Lol be careful, some kpop could be singing your fave anime's theme song.
I personally got into kpop 2007-ish. Unfortunately, I immediately lost interest thanks to horny fangirls who like to sexualize everything. Shippers
Anime-only fans are the worst, though. That fandom attracts people with the lowest IQ. They seem to have all sorts of mental issues too. Manga-only fans are a tad bit better, and they usually resemble "normal" people the most.
Also, just because you're into Asian entertainment it doesn't mean you're appropriating their culture. Young somalis are more likely to to appropriate the hephap culture than the Asian pop culture. Just saying.
Anyhow, all fandoms be they into kpop, drama, anime, gaming, football, and so forth, are all toxic as hell. Period.
