If some people were walking around waving a foreign flag and then telling people what to do and it was all caught on video, some group with guns would then decide they had to be vigilantes and go out and hunt down anybody that looked like the people with the flags in the video. So, we would get another group of mass shootings all directed at the people that looked like the people carrying flags in the video. 

It seems like over there, there is a bit of anger about it but you guys will just invite a weird Canadian guy onto the telly and crack some jokes about it and talk about having a free country, while the Canadian guy talks about how horrible Canada is. 

Here it would immediately become an excuse to shoot some more people. It's like declaring hunting season is now open on the Chinese. There would be militia groups wandering around in states like Michigan, Ohio, and Georgia looking for anybody that was Chinese. Every Chinese restaurant would be shutdown, and Chinatown in every city would be a ghost town. In fact, since the videos are on Youtube we probably already have nutters in the states discussing where to go to be able to shoot the most Chinese people in one go and it did not even happen here.

This is why here in the states, we do have to be careful what we say, because we actually do have roaming mobs of lunatics just looking for any reason to pull the trigger on someone.
