Leftists would like to change everything about the U.S. After they got done, nothing of what people knew as the old U.S. would be recognizable.
Fortunately, the number of people who are leftist is still very small.
Unfortunately, their numbers and ideas are being more and more accepted by younger Americans who readily believe the lies told them by libs and leftists about an unjust America.
This goes back to our schools where children are taught about all the bad things in American history without balancing with the mostly good. If you are taught that every person responsible for making America was evil, wouldn't you want to change it as well?
Of course, the logical result of rejecting virtually everything in America's past is all non-Indians going back to Europe and other places. To which I say: leftists, you go first.
