Lisa’s not really hated in Korea lol online hate warps everyone’s perception. By Pann standards, a million Kpop girls are hated in Korea
But I’d assume Lisa’s lesser popularity in SK is mostly just cuz she looks distinctively non-Korean (she was the first BP member I could differentiate) so automatically Koreans probably gravitate towards the other three because of xenophobia towards SEA. Meanwhile Hanni definitively could pass as Korean.
I don’t think it’s a visual problem tbh, even if Lisa looks distinct she fits KBS quite well (especially her body which gets a lot of praise). I think it’s mostly the fact that the other three members have something else that draws the GP in (Jennie for her cute-sexy appeal, Jisoo for her near-perfect visuals, and Rosie for her voice) so Lisa ends up at the tail-end because she’s of a different nationality unfortunately. She’s got massive international popularity to counter that tho
