re: George Washington, Ulysses S. Grant, Francis Scott Key....

Like I said, the genie is out of the bottle at this point. The question is how far these people are going to be allowed to go before everyone else is willing to put their foot down and say enough is enough. I suspect that demanding the destruction of iconic national monuments would cross the line, but I'm really not sure anymore. The media is pretty much entrenched on either extreme end of the issue depending on the network, which kills any chance of a middle ground ever being found.
