This [1] is the entire, in context, video of the controversy in question. Unfortunately I've yet to find a complete translated transcript so I am left on relying on potentially unreliable online translations. From what I've read the casters say 'Go ahead and say those 8 words and we'll wrap up here. There's nothing else to talk about. Let's lower our heads.' He then screams 'Liberate Hong Kong, revolution of our time.' Guess that's 8 words in [presumably?] Cantonese. This was done while wearing a gas mask. The tournament casters then laugh and clap.
This is actually the thing that most frustrates me about so many issues. How can people justify forming opinions on these things without seeing everything in context? Why isn't this entire video, alongside a professional translation, a part of every story on the topic? Of course providing in context video gets downvoted, because it makes the issues look less black and white. But that to me is the clearest example of idiocracy. We should not seek to create Hollywood villains and heroes in nuanced issues. We should consider these issues as they are, which invariably tend to be a million shades of gray as opposed to black and white.
