if you don't think there are male fans who don't like that jennie twerks on stage, you're wrong. kpop has a surprising amount of fans who are white supremacist incels who fetishize asian women. they want asian women to be docile and submissive and pure and uncorrupted by feminism, so when they see stuff like jennie twerking they become genuinely angry.
Yeap, I've definitely seen this happen. Kpop international male fans getting rabidly angry when Jennie (and others like Soyeon) don't act like the "docile and submissive and pure and uncorrupted by feminism" fantasy visions of asian females they have in their head. There's also this whole moronic discourse on how "pure" idols are in kpop incel communities.
And heaven forbid a female idol gets a tattoo. She's absolutely the WORST apparantly.
