we are still in a state of civil war, so this is like the 100th thing that we are doing to each other to piss each other off.
You know we use to fire shells onto each other's shores not long ago, there's actually a dude that makes knife sets from the shells in Taiwan, I got a set, very good quality.
Flags are different? No shit, they are a Chinese government and so are we. IF we had the same flag we be the same government.
Vichy France flag is not the same as De Gaulle France flag.
As to offend me, the fact most Americans don't know where Hawaii is on a map or how many Senators come from one state, I say American ignorance and arrogance is not offensive, but hilarious.
