Yep, a lot of stuff was erected during the depression. I know about the WPA but I think the art and cultural stuff was a separate program.
It won't matter who built it or erected it. The criteria for removal is very simple.
The brakes will get applied by the left once they can feel the strength to bother. Some will certainly go back up in little stupid ceremonies with apologies.
Be thankful that the left is in reality not just a bunch of talk radio "Ditto heads". Their opinions are far from homogeneous and it takes a little more time for things to filter down.
The past is important to me, very much, just I would never hang on to a made up version of it for long. As my mom used to say, time passes and things change, usually for the better. America has a lot of unfinished business to work out.
