>>22510811There are two kinds of Polka anties in JP.
One is because She is the opposite of what most JP cucks envision for a waifu. She is the opposite of the ideal JP girl who are shy unassertive tsundere. Since Polka is the complete opposite of that, she tends to be very loud in large collabs and drowns out other people's oshis. She kind of hogs the spot light sometimes if you know what I mean. Her distinct voice and laugh also marks her out and people may think she is rude but she's just very energetic. Japanese social norms plz anstand.
The second type are usually related to her coming from upd8. In Japan, loyalty to ones group / corp is a important aspect of how people interact and view each other. Being a tribal fag is the accepted norm over there. Imagine that the most hated rival player to your home team suddenly quit their team and signed with your home team. Lots of anties early on were saying things like how Polka is not real Hololive because she is from a rival agency.
