How exactly should a spectator handle it? Yes, I was there. I cant interrupt a match, especially when it doesn't involve me directly. I saw pats on the back and congratulations on a match that was won. Do I know what happened behind closed doors? No. I don't.
In the heat of battle, so to speak, maybe it wasn't looked at in the same light that it would when you watch the video. I can tell you are a proud community, and that you don't like the criticism. But maybe, just maybe it wont ever happen again because somebody like me stood up and said they saw it and it wasn't right and it shouldn't be ignored.
