In my world, no. A government building flys the flags associated with it. While it's easy to be on the side of a federal building flying the flag of Ukraine, or one state flying the flag of another going through a tragic event, supporting that would also allow government buildings to fly the Israeli flag, or the confederate flag or a MAGA flag. You don't think that confederate sympathizers in the south would claim to be marginalized and the confederate flag flying at the Mississippi statehouse would make them feel welcome? It's a knife that cuts both ways.

I want marginalized people to feel welcome in their communities, but I don't believe the flagpole of a government building is where to do it. The floor of the government building is.
