We don't have to revere every part of our heritage. This is just a normal part of the cultural change that happens in any country. Some things in our history end up monumentalized as statues for public veneration, while the rest is recorded in the history books. In every stage of country's development there will be people who wish to hurry along the progress and those who aren't ready to move yet. The terms that most accurately reflect this divide, as far as I have seen, are 'progressive' and 'conservative'. No need to bring in 'alt' anything. If part of what you want to conserve is the racist, nationalistic streak that motivated some of our founders, you are a conservative who is also a racist and a nationalist, not an alt-anything. If the progress you want to make involves vandalizing property and circumventing the existing process for having monuments removed, you're a progressive who doesn't have enough patience. Those are the sides of this argument: one side is wrong because their entire worldview is wrong, the other is wrong because they are too hasty. They are not equally wrong, nor are they wrong in ways that place them at some kind of moral stalemate. The racist conservatives are worse than the impatient progressives.
