I’m married to a proud Welshman. They fly their flag with pride and nobody would ever suggest that it shouldn’t be flown in any situation. And it’s the same in Scotland
There are very many people in Scotland who feel the Saltire has been hijacked and now represents a political party rather than the nation. Some see this as a positive, others a negative. It means though that the Saltire no longer represents the nation as a whole which is a great shame. As to what many Scots call the Union Flag (as already stated on GN) it's certainly very divisive.
I've no problem with flag flying but find it perverse that the reason for Nottingham Council instigating this is supposedly due to the disrepair of the flag brackets, staffs, etc. Surely the disrepair of more essential services should be a priority. In my area that would be welfare, pavements, roads, libraries etc (not necessarily in that order).
Here is a list Nottingham Council have apparently released of where the Union flags will be sited. One each side of the road apparently.
I guess we will find out how divisive they are, or not, if they remail flying or are removed/defaced.
