The status quo isn't validated because it is what happened when one side won. That's not what's being argued. Might doesn't make right.
What's being argued is that that is how every status quo has been arrived at. You cannot bitch that any particular nation was made by conquering others because that is how they all were made. It isn't oppressor vs victim it's winner vs loser.
So the current argument for tearing down any statue of anyone is an argument that calls for tearing the down every statue of everyone.
