I can understand being told to remove political etc stuff. But this is the national flag of the nation of the window in question is it not?
I don't understand how the f#$k you can be asked to take down your national flag. It is everyone's patriotic duty to fly the flag of their nation!
The world is turning upside down again. If you are going to offend someone with the national flag of any nation, we should look at the offendee and they should F$%K OFF! to somewhere where they will not be offended!
