/vt/ - Virtual Youtubers

Why do Americans love to bully the talents they are meant to be supporting. Even the English and Australian viewers who entirely thrive on banter in real life don't do this to their oshis.
Meanwhile Americans spam bad memes in unrelated chats like it's some game show catchphrase. They'll do it every chance they get even if it's only barely related. Then the rest of them will jump in and spam it.
I understand this is a twitch chat thing but I would go further and say this is an American thing.
Will Americans ever stop hurting the oshis they supposedly care about?
Why are EU and Japan audiences so much better than them?
