Then you shouldn't have a problem burning the UN flag.
The un is not a country, but I get your point. My point is simple. Don't be a hypocrite. You don't like them burning our flag, neither do I. How is burning their flag going to make you feel better?
Go ahead and burn the UN flag...just know that when the NWO UN government is in power, when they see footage of you burning their flag, they will probably hunt you down, arrest you, and detain you indefinitely.
