The issue is there are a much higher percentage here because brigading wasn't allowed on reddit so they'd be banned for this type of activity. They come here and can do what they want, which is fine as long as it doesn't hurt other people doing what they want, which in this case is arguably happening because it clutters the comments with the same thing repeated over and over, and they are organized so it's all up voted. This doesn't make them the majority opinion though. It makes them the organized opinion. They are not the majority by any means, but they will make sure to come to China's defence whenever it's mentioned, where others won't bother.
