It will never end. Anyone who came before will always be seen as "problematic"
The quotes on that are bullshit and you know it. The US is built on stolen land. That's not "problematic", it's problematic.
Dismissing the plight of North America's Indigenous peoples as though it's mere pedantry is equally as shameful as the continued history of African-American racism.
It's why the 2nd and 3rd option in the poll seem like they fit a VERY narrow difference in criteria unless you conveniently omit the Indigenous.
We'd have to remove every statue ever.
OK? Remove them from public spaces. Public statues are intended for contextless veneration and commemoration of the person depicted, plain and simple. It's why the ancient cultures made so many of their gods and heroes and why these ancient cultures also tore so many of them down, either due to cultural erasure from colonial conquest (see: Judeo-Christian missionaries and conquerors tearing down/destroying "Pagan" imagery) or due to changing norms within their own cultures.
A statue's existence does not and should not guarantee its permanence if it no longer represents the values that the culture holds now. I'm not an advocate for destruction per se, but I do advocate for removing them from public spaces and thus revoking the contextless veneration of the person depicted. But in the absence of governments doing so, people are gonna destroy them.
And some of them should absolutely be melted down for their base metals, because they shouldn't have existed to begin with, as with the flood of Confederacy statues that were commissioned after a major push from the Daughters of the Confederacy in the late 1800s to early 1900s, simply to build a grand imposition against black rights during the Jim Crow era.
And hey, some of them likely can stay, so long as those individuals depicted were on the right side of history. My home town has a statue of Gordie Howe. His and his wife's ashes were interred inside the base of the statue after they passed; it's essentially a gravesite now. Even if Howe suddenly came to be discovered as a bigot or a horrid man by some standard or another, THAT might be the single case where a statue might need to stay standing.
Culture changes and who or what we venerate must change with it, as it has been for countless human centuries. Simple as that. These individuals aren't going to be forgotten, the Information Age makes damn certain of it, so let's stop offering monuments of veneration without context if they no longer warrant that.
Take them down.
And stop saying erasure. These guys are intrinsically linked to the history of the country, they're always going to be in the books/museums/schools. Statues and monuments are for celebration.
Bingo.
