That is absolutely awful (IMO). How dare "they" deny anyone the right to fly their national flag. All the sacrifices made fighting and dying under a nations flag. Gosh, that really really bothers me for you!
What the heck would anyone be thinking to make that a policy or even a bloody recommendation.
Do you guys not put the flag out on the graves of soldiers throughout the year? Will this also be denied! What if, in protest, you start flying the old Russian flag or the flag of Pol Pot!
I'm very sad for you!
